Abstract
Recycled rubber is not considered as an option for the production of recycled concrete as it decreases the strength parameters of concrete in a major outsource. In this research work, a new kind of testing method is taken into consideration for the production of precast members. Compression casting is mainly considered for the production of compressed concrete precast members. Chipped rubber is used as an option over natural coarse aggregate. Chipped rubber at normal instance decreases the durable properties of concrete but the combination of compression testing as well as chipped rubber replacement can note be neglected. Chipped rubber is replaced at 0–50% with natural coarse aggregate. The freshly prepared concrete is condensed in a specially designed mould and after that compression, casting technique is applied over it. Samples of both compressed chipped rubber as well as uncompressed chipped rubber are prepared and then tested further for compressive strength test, modulus of elasticity test, water absorption test. Scanning electron microscopy, as well as cost analysis of controlled concrete, compressed rubber concrete and uncompressed rubber concrete, is performed to get the ultimate benefits of this type of concrete. Compressive strength test results show that the mix with 30% replaced of ripped rubber under compression gives the maximum results of all. Also, the results of elastic modulus were maximum for the same. Cost analysis shows that compressed rubber concrete shows major benefits in the case of precast concrete members. This proposed method should be implemented by the concrete industry from an environmental point of view .
