An experimental study on strength and durability properties of self-compacting and self-curing concrete using light weight aggregates

ABSTRACT

Concrete is a material that is often used in the construction industry due to its strong compressive strength and durability. Currently, a lot of research is being done to find new ways to increase performance. One of these ideas is what led to the creation of self-compacting. Concrete is accepted as the most cutting-edge development in the concrete building industry. Currently, a lot of research is being done to find new ways to increase performance. Self-Compacting Concrete is becoming more and more popular for usage in overloaded reinforced concrete constructions with difficult casting circumstances. High rise buildings with multi storey construction need light weight concrete so there is a need to investigate on lightweight concrete. The mechanical and physical properties of self-compacting, self-curing, and light-weight concrete are created in this study by replacing natural aggregate with fly ash and expanded clay at percentages of 0%, 10%, 20%, 30%, 40%, and 50%. Calotropis gigantia, a self-curing agent, is incorporated in 4% of the volume of cement and super plasticizer in order to maintain the workability of concrete of M30 grade concrete. The mix proportion of light weight self-compacting concrete is 1:2.04:1.17 with water cement ratio of 0.4.
