A Study of Cost-effective Building Materials and construction techniques for warm and humid climate in India
Chapter 5 Cost-Effective Technologies for the common man Any house is made up of two parts: the foundation, or substructure, and the superstructure. The superstructure is divided into four sections: walling, roofing/flooring, finishing, and doors and windows. Our collection includes sections on numerous housing solutions. We are combining traditional, vernacular, and alternative systems. The alternative solutions shown here are not only costeffective, but also energy-efficient, environmentally friendly, and in harmony with nature. They also assist in the establishment of medium to small businesses that rely on locally available materials.

It can cut building costs by up to 40%. The benefit of this is that the depth of the foundation may be substantially lowered in soft soils; the downside is that the end piers must be carefully fortified by buttresses to avoid the push to arch action tending to tear the piers connection. (B.M.T.P.C., 2015) 5.2 Plinth It is recommended that the plinth be 1 foot above ground level and built with a cement mortar of 1:6. The usual plinth slab of 4 to 6′′ can be eliminated, and in its stead, brick on edge can be utilized to save money. The cost of plinth foundation may be decreased by 35 to 50 percent by using this approach. (B.M.T.P.C., 2015) 5.3 Brickwork Bricks made from black cotton and poor soil stabilized with fly ash were used in a 1:6 cement mortar. Rat-trap bond brickwork in a cement lime mortar/1:1.5:3 cement sand mortar ratio of 1:2:12. Masonry is made of hollow concrete blocks and cement mortar. Masonry is made of compressed mud bricks in mud mortar. Stabilized mud bricks in stabilized mud mortar (4 percent cement or lime). Sand lime brick walls with a cement mortar ratio of 1:6. Sand block FAL-G with cement mortar 1:6.(B.M.T.P.C., 2015) The bond is the manner in which bricks overlap when being laid. The rat-trap bond
