Expermental Study on the Mixture Ratio and the Compressive Strength of Concrete with Recycle Crushed Brick Coarse Aggregate

Abstract:

Considering the high absorption of water is a distinctive feature of recycled crushed bricks coarse aggregate, the mixture ratio text of recycled concrete using crushed bricks as coarse aggregate is carried out, and the compressive performance is studied.The resert indicate , the strength grade of recycled concrete which using bricks as coarse aggregate can reach C20 and C25, characterisitic value of cubic concrete compressive strength at the age of 28 days are 21.2MPa and 27.55MPa;Based on regression analysis of test data , the formulas which estimated the strength of recycled coarse aggregates concrete are given out. Calculated values are in agreement with the measurement values, which can provide a reference for engineering application.
