Abstract
Due to high cost of aggregates, cement and steel in plain regions of Pakistan, low income people
are unable to get their houses constructed using Reinforced Cement Concrete (RCC). In this study,
potential of baked clay as an economical material of building construction is investigated in order
to replace normal concrete. For this purpose, compressive strength and tensile strength of baked
clay fired at 1000˚C were determined. The results show that the compressive strength and tensile
strength of baked clay are about 65%, and 80% more than those of corresponding values of nor-
mal concrete, respectively. This implies that by utilizing reinforced baked clay instead of RCC,
saving of cement aggregates and reinforcing steel could be achieved.

1. Introduction
Provision of houses to low income people is a challenging task in Pakistan since its independence in 1947. This
is due to increase in cost of traditional materials of building construction such as cement, aggregates and steel. It
is, therefore, responsibility of engineering community to investigate possible use of local and low cost materials
of building construction so that the people could be able to get their houses constructed at an affordable cost.
The indigenous and low cost materials of construction include wood, clay and stone. Among these materials,
