Abstract
Concrete is the most widely used building material. It has desirable Engineering properties, can be moulded into any shape and more importantly is produced with cost effective materials. Large numbers of mineral admixtures, which are waste products of other industries, are being beneficially used in making quality concrete. The increase in durability along with strength of concrete will lead to the use of high-performance concrete which will be more beneficial for environmental attacks on the structure. High-performance concrete involves variation of different parameters like water-cement ratio, use of mineral admixture, chemical admixture, temperature, curing regime, etc. The mechanical and environmental performance of concrete was observed to be depending on various types of material used in the concrete. The properties of concrete depend on packing of grains and type of curing regime. Alternative concretes are needed to reduce the significant environmental impact of ordinary Portland cement concrete construction. Although fly ash as a partial replacement for cement has been utilized for many years, it has been almost exclusively used in low volume percentages, such as 10 or 20% cement replacement which reduces the cost of concreting but it effects on concrete inversely. In this study cement is partially replaced by ALCCOFINE and fly ash for M60 grade of concrete. The compressive strength of concrete with OPC and ALCCOFINE and it has been found that the strength of concrete got increased by 10% with partial replacement of cement by ALCCOFINE and the cost also reduced. HPC is designed to have better mechanical properties and a higher resistance to chemicals than conventional concrete. This study is focused to investigate the strength parameters of HPC with partial replacement of cement by Alccofine with optimum 10%. Poly Carboxylic Ether is a type of super plasticizer which is used to improve flow and workability characteristics. For the optimization of mixtures, compression strength was tested.
