Abstract In India, traditional clay brick is the most common filler material used in building. The materials used in construction have a significant influence on both the constructed environment and the project’s ultimate cost. Autoclaved Aerated Concrete (AAC) has recently emerged as a viable alternative to clay and fly ash bricks. In this work, a comparison of clay bricks and AAC blocks is explored. Although AAC blocks have been utilised in building since 1924, they now account for just 16-18% of all construction in India. AAC blocks have desirable mechanical qualities in proportion to their low bulk density, improved thermal and acoustic properties, light weight, and ease of installation, making them an obvious alternative to replace traditional clay bricks. The purpose of this study is to demonstrate the potential of AAC blocks as an infill material to replace clay bricks and to encourage its usage in construction to create more energy efficient and sustainable structures. AAC blocks’ potential as an infill material in hilly areas is discussed.

Abstract: Based on the experimental investigation of quasi-static test of 5 AAC block walls and 1 clay brick wall, the hysteretic behaviors were analyzed on the basis of the experiments. The collapse resistant capacity of walls which were used two different materials was compared. It was shown that the seismic and collapse resistant capacity of autoclaved aerated concrete was improved obviously and reached the level of clay brick wall basically, which was added constructional middle column.

The Impact

This research investigated the impact of agricultural biomass additives (Argan shell) on the thermal and physical properties of fired clay bricks for building application. The objective of the study is to characterize the selected materials from molecule up to the final materials used in buildings. The materials used in this study, are soil and Argan shells, locally available materials for brick making. The Argan shells were grinded and then added to the clay mixture. The Clay brick shows a formation of pores during the firing process up to 1050°C. As results, the bulk density of the clay bricks decreased due to the pores formation. On the other hand, the thermal conductivity of the clay bricks was reduced by 53% using 20wt% of the biomass additives.

Masonry Units

Autoclaved aerated concrete (AAC) blocks are the lightweight and green concrete blocks that are composed of cement, fly ash, lime, gypsum and aluminium powder. Depending on its density AAC consists of up to 80% of air by volume. Due to their low density and lightweight Autoclaved aerated concrete blocks exhibit so many favourable physical properties that these have got attention from all around the globe. Due to these enhanced properties Autoclaved aerated concrete blocks are extensively used as masonry units in all types of construction. On one hand AAC blocks have no comparison with other types of masonry units in terms of physical properties but on other hand AAC blocks are found to have low compressive strength relatively. In this study an attempt has been made to study the influence of Alkali-Resistant Glass Fibre additive on the physical and mechanical properties of Autoclaved aerated concrete blocks. Four sets of samples were cast and named as A, B, C and D with the fibre additive contents as 0%, 0.1%, 0.2% and 0.3% respectively (by dry weight of all the ingredients).Each sample set consisted of three specimens and the average value of the three samples were taken. For example, the average value of the three specimens- A1 , A2 , and A3 was taken as A and so on. Fibre additive influenced the aeration process of Autoclaved aerated concrete by increasing the rising/aeration time by 8%. The investigated fibre additive increases the compressive strength by 0%, 10%, 24% and 13.8% respectively to the added fibre contents of 0%, 0.1%, 0.2%, and 0.3% respectively. The optimal content of Alkali-Resistant Glass Fibre additive to be added for obtaining the highest compressive strength is 0.2%. Further investigations have shown a slight variation in density (about 0.2%) between the normal and modified Autoclaved aerated concrete blocks.

Materials Used

The clay brick is one of the oldest building materials, and as the use of waste in the bricks can reduce clay consummation and the environmental burden due to the accumulation of waste, the present study was chosen, the addition of mineral and organic waste to the clay brick. The added value of this work, which was carried out within the Institute of Building Materials at VGTU, is that the mixture studied is very special, because the raw materials used are: − Yellow Clay (C) from Fez which is used only in the field of pottery; − Pyrrhotite Ash (PA) which is a mineral waste produced during the manufacture of sulphuric acid from the roasting of pyrrhotite ore. This waste is stored in the open air since 1982 and until now it doesn't have any specific use; − Cedar Sawdust (S) is an organic waste regenerate by the artisanal sector from Fez. The bricks’ technological properties depended on the amount of ashes used. So, adding 5% S to the mixture (20% PA – 80% C) gives rise to a new material that is light, porous with a natural brick red colour. Most importantly, this material exhibits mechanical strength according to the standards of a terracotta brick.
