—By far the most common coarse aggregate used in concrete is obtained from natural rock, but type of rock suitable for concrete making is not available everywhere. In Tripura a north-eastern state of India brick aggregate concrete are used conventionally for ordinary concrete due to scarcity of aggregate from natural source. Due to advancement of concrete technology and to fulfill the durability requirement it necessitated to use standard concrete, for which only stone aggregate is used, as a result, cost of construction has been skyrocketed as these are transported from other states. Making good quality concrete with finest sand (grading zone –IV as per Indian code IS:383-1970) is itself a challenge, moreover there is unavailability of natural coarse aggregate locally. Therefore, in this paper a concerted effort has been made to check the feasibility of use of brick aggregate made of locally available brick in standard concrete (M25 to M55 as per IS:456-2000). High water absorption (12% to 20% by mass) of brick aggregate is a major problem to use it in the actual work, thus an attempt has been made to suggest a realistic solution for real field application. An experimental study has been conducted to check various strength parameters, workability and fire resistance of brick aggregate concrete. It is observed that standard concrete can be made with crushed brick aggregate which are also having very good heat resistance upto a temperature of 6000C.
