Provides basic steps and general guidelines for the correct use of plaster and render. Includes suggestions of several preparations available to aid this process.

Low carbon repair epitomises sustainable maintenance management for heritage buildings. However, there is little recognition of this aspect, coupled with impractical assessment of repair impact strategies. This paper aims to present a decision-making process based on life cycle assessment (LCA) approach of lime plaster repair options for heritage buildings.

Calculation procedures of LCA were carried out to enable sustainable maintenance management appraisal for heritage buildings upon embodied carbon expenditure expended from lime plaster repair during the maintenance phase.

Calculation procedures could be understood as a carbon LCA of lime plaster repair and recognised in reducing CO₂ emissions. This underpins low carbon of lime plaster repair in achieving sustainable maintenance management of heritage buildings.

It must be emphasised that the LCA approach is not limited to heritage buildings and can be applied to any repair types, materials used and building forms. This supports environmentally focused economies and promotes sustainable maintenance management solutions.

The LCA approach highlights the efficiency of repair impact strategies through evaluation of low carbon repairs options.

The LCA approach results show that low carbon repair, contextualised within maintenance management, relays the “true” embodied carbon expenditure and stimulates sustainable development of heritage buildings.

The purpose of this paper is to assess the effects of cement‐ and earth‐plastered straw bale walls against the appropriate vertical loads.

The effects of contact between two common types of plasters and the stacked straw bale by the optimal design analysis have been assessed in this work with the use of finite element method.

Cement‐ and earth‐plastered straw bale walls have shown adequate resistance against the appropriate vertical loads and showed that the earth‐plaster can bear higher stress than the cement plastered straw bale. There is the implication that the collapse or response of the earth‐straw bale wall will be significantly higher compared to that of cement‐straw bale wall.

The stress stability obtained of the analytical walls is adequate after using the best fit variables for the wall height and thickness.

The paper shows that the allowable stresses of 70.14 kN/m² for cement plastered straw bale wall and 73.14 kN/m² for earth‐plastered straw bale wall are higher than the calculated stress values using SAP2000 of 18.836 and 64.2 kN/m² for cement plastered straw bale wall, respectively.

This paper seeks to test the applicability of lean principles to simple construction processes using discrete‐event simulation.

Quantitative construction data and process mapping of plastering and block‐laying processes were first gathered and established from construction project through field observation and interviews with those involved in the selected projects. Then a simulation model was built to mimic the aforementioned processes to study the impact of certain lean principles. The simulation models became like an experimentation tool where lean principles (e.g. focus on actual objects and map the value stream) were introduced to evaluate their impact on such processes.

Lean principles are effective not only in complicated processes, as proved in previous studies, but also in simple processes. Enhancing the flow of construction materials means the less time they will spend in the value stream and as a result the leaner a process will be. In fact, simple processes are good candidate for lean improvements.

Simulating lean principles did not bring different construction processes to the leanest level of performance. There are other factors that govern each process. Rework, uncertainty, labor skills, site conditions and location are some examples of such factors that need further analyses for leaner construction processes.

Many studies focused on complicated processes to investigate the applicability of lean principles to construction. Results of these studies affirmed the great potentiality of such principles in improving construction processes. This study readdressed the issue of lean applicability to construction by focusing on simple processes, which are block‐laying and plastering.

Discusses the techniques of repair and conservation of early lime‐based plasterwork. Considers the problems of cracks in plaster, detachment of plates of plaster, the breaking up of plaster, and the stages in the repair of wall panels and overmantles and the re‐hanging of ceilings. Concludes that since old plaster cannot be reproduced, careful consideration procedures are necessary, although complete plasterwork is best left alone.

The present work highlights the outstanding properties of Cannabis sativa that can be harnessed for various utilitarian functions and its climate friendly properties.

In this paper, the authors reviewed current research on all possible utilities from household work to manufacturing of various products that are environmentally sustainable. The authors have presented some of their research on this materials and also exploration of hemp as an archaeological material based on the findings from wall paintings of Ellora caves.

There are references of hemp use in mixing with earthen/lime plaster of western Indian monuments. Around 1,500 years of Ellora’s earthen plaster, despite harsh climatic conditions, survived due to the presence of hemp in the plaster that adds durability, fibrosity and its capacity to ward off insects and control humidity. Furthermore, the outstanding quality of Cannabis as carbon sequestrant was harnessed by Indians of ancient times in Ellora mural paintings.

This work discusses some relevant literature on the potential use of hempcrete aligned with Agenda 2030 of sustainable development goals.

There are several research going on in producing sustainable materials using hemp that have the least environmental impact and can provide eco-friendly solutions.

The authors impress upon the readers about multifarious utility of the hemp and advices for exploration of this material to address many environmental issues.

This paper presents both review of the existing papers and some components coming directly from their laboratory investigations.

The purpose of this paper is to evaluate the performance of 3D printed materials for use as rapid tooling (RT) molds in low volume thermoforming processes such as in manufacturing custom prosthetics and orthotics.

3D printed specimens of different materials were produced using the Z‐Corp process. The parts were post processed using both standard and alternative methods. Material properties relevant to the 3D printed parts such as pneumatic permeability, flexural strength and wear rate were measured and compared to standard plaster compositions commonly used.

Three‐dimensional printing (3DP) can replicate the performance of the plaster materials traditionally used in prosthetic/orthotic applications by using modified post process techniques. The resulting 3D printed molds can still be modified and adjusted using traditional methods. The results show that 3D printed molds are feasible for thermoforming prosthetic and orthotic devices such as prosthetic sockets while providing new flexibility.

The proposed method for RT of a mold for prosthetic/orthotic manufacturing provides great flexibility in the manufacturing and fitting process while maintaining proven materials in the final device provided to patients. This flexibility increases the value of digital medical records and efforts to develop model‐based approaches to prosthetic/orthotic device design by providing a readily available process for recreating molds. Depending on the needs of the practitioners and patients, 3DP can be incorporated at a variety of points in the manufacturing process.

Encourages the saving of distressed stucco and fibrous plaster ceilings of merit and shows that repairs are able to be carried out in nearly all cases by use of traditional materials, all of which are available in one form or another. These ceilings are able to be reinstated/ conserved using plaster firms and conservationists, with specialist advice available supported by many years of experience. Such ceilings are to be found throughout the UK, ranging from small residences to theatres, historic houses and palaces. It is indicated that repair of the ceilings must be carried out as soon as possible by the use of qualified artisans and conservators using methods, some being described, with emphasis on calling in experts at an early stage.

This study aims to investigate the effect of high temperature (600°C) on the compressive strength of concrete covered with a mixture of polypropylene fiber and gypsum plaster (PFGP).

To study the compressive strength of concrete specimens exposed to temperature, 16 cubic specimens (size: 150 mm × 150 mm × 150 mm) were made. After 28 days of processing and gaining the required strength of specimens, first, polypropylene fiber was mixed with gypsum plaster (CaSO4.2H2O) and then the concrete specimens were covered with this mixture. To cover the concrete specimens with the PFGP, the used PFGP thickness was 15 mm or 25 mm. The polypropylene rates mixed with the gypsum plaster were 1, 3 and 5 per cent. A total of 14 specimens, 12 of which were covered with PFGP, were exposed to high temperature in two target times of 90 and 180 min.

The results show that the PFGP as covering materials can improve the compressive strength lost because of the heating of the concrete specimens. The results also show that the presence of polypropylene fiber in gypsum plaster has the effect on the compressive strength lost because of the heating of the PFGP-covered concrete. The cover of PFGP having 3 per cent polypropylene fiber had the best effect on remained strength of the specimens.

The cover of PFGP having 3 per cent polypropylene fiber has the best effect on remained strength of the PFGP covered specimens exposed to temperature.
