An experiment on strength and capillary water absorption of concrete made with brick fine aggregate and silica fume

Sustainable resources management and development have been at the forefront of an important issue concerning the construction industry for the past several years. Specifically, the use of sustainable building materials and reuse waste materials is gaining importance and becoming commonplace in many areas. In the present study the hardened properties like compressive strength, split tensile strength, and also durability properties like porosity, and CSAT test was carried out on bricks fine aggregate concrete. The percentage of bricks fine aggregate that partially and fully replaced by fine aggregates by weights were 0%, 10%, 20%, 30%, 40%, and 50%. Experiments were conducted for both Ordinary Concrete and bricks fine aggregate Concrete with different percentages of bricks fine aggregate (BFA). It is observed from the experimental results and its analysis, that the compressive strength of concrete, splitting tensile strength of concrete increases with the addition of low Percentage of bricks fine aggregate. The results show that the optimum replacement of recycled bricks fine aggregate with fine aggregates was 20%. Up to 20% replacement, it is possible to gain the same strength as conventional concrete. Beyond 20% replacement the strength results following a decreasing trend. Moreover, capillary suction absorption increasing with increase in replacement of BFA. It was also found that the bricks fine aggregate concrete perform well up 20% replacement of BFA with fine aggregate. It was clear that firstly porosity increasing in 7 and 14 days after decreasing with a long period and minimum porosity obtained with mix 80+20A+10%SF.
