Highly sophisticated digital technologies have distanced architects and designers from intimate and immediate hand-drawing practices. Meanwhile the changes they rapidly bring come with undetected changes in cultural and social norms regarding the built environment. The growing dependence on computers calls for a more holistic, socially inclusive and place-responsive design practice. This paper aims to shed light on what we are losing in the design process as we rapidly transition to communicate architecture using digital media. The authors contemplate the paradigms in which the human body and physical objects still play an important role in today's design environment.
The paper looks at current trends in developing and establishing “computer imaging” within architectural education, and the architectural profession through parametric design and the area of sustainability. In order to reveal novel and hybrid ways of architectural image-making, it also looks into art forms that already experiment with bodily practices in design by taking an artisanal animation project as a case study.
The renewed longing for craft, haptic environments, tactile experiences and hand-crafted artifacts and artworks that engage the senses can be exemplified with the success of the documentary Last Dance on the Main, an animated film on the endangered layers of human presence in one of Montreal's downtown neighborhoods. The open possibilities for creative hybridizations between the handmade and the digital in architecture practice and education are exposed.
The influence of film on the perception and consequent design of cities is well documented. There is little literature, however, on how the materiality and process of artisanal film animation can provide alternative, if not additional, insights on how to communicate various aspects of the built environment, particularly those rooted in the human body. Furthermore, handmade film explores a broader understanding of sustainability, which includes considerations for social and cultural contexts.

Concrete is a building material widely used for the infrastructural development. Cement is the binding material used for the development of concrete. It is the primary cause of CO2 emission globally. The purpose of this study is to develop sustainable concrete material to satisfy the present need of construction sector. Geopolymer concrete (GPC) is a sustainable concrete developed without the use of cement. Therefore, investigations are being conducted to replace the cement by 100% with high calcium fly ash (FA) as binding material.
High calcium FA is used as cementitious binder, sodium hydroxide (NaOH) and sodium silicates (Na2SiO3) are used as alkaline liquids for developing the GPC. Mix proportions with different NaOH molarities of 4, 6, 8 and 10 M are considered to attain the appropriate mix. The method of curing adopted is ambient and oven curing. Workability, compressive strength and microstructure characteristics of GPC are analysed and presented.
An increase of NaOH in the mix decreases the workability. Compressive strength of 29 MPa is obtained for Mix-I with 8 M under ambient curing. A polynomial relationship is obtained to predict the compressive strength of GPC. Scanning electron microscope analysis is used to confirm the geo-polymerisation process in the microstructure of concrete.
This research work focuses on finding some alternative cementitious material for concrete that can replace ordinary portland cement (OPC) to overcome the CO2 emission owing to the utilisation of cement in the construction industry. An attempt has been made to use the waste material (high calcium FA) from thermal power plant for the production of GPC. GPC concrete is the novel building material and alternative to conventional concrete. It is the ecofriendly product contributing towards the improvement of the circular economy in the construction industry. There are several factors that affect the property of GPC such as type of binder material, molarity of activator solution and curing condition. The novelty of this work lies in the approach of using locally available high calcium FA along with manufactured sand for the development of GPC. As this approach is rarely investigated, to prove the attainment of compressive strength of GPC with high calcium FA, an attempt has been made during the present investigation. Other influencing parameter which affects the strength gain has also been analysed in this paper.
