废弃混凝土破碎成小块体,将替代率分别为0%,20%,和30%的再生混凝土块体和现浇混凝土混合放入200 mm×200 mm×200 mm的立方体试模中,制成再生混凝土混合试块。对再生混凝土混合试块进行立方体抗压试验,测出不同块体替代率下混凝土试块的抗压强度,试验结果表明随着再生混凝土块体替代率的增加,再生混凝土混合试块强度降低。
廢棄混凝土破碎成小塊體,將替代率分彆為0%,20%,和30%的再生混凝土塊體和現澆混凝土混閤放入200 mm×200 mm×200 mm的立方體試模中,製成再生混凝土混閤試塊。對再生混凝土混閤試塊進行立方體抗壓試驗,測齣不同塊體替代率下混凝土試塊的抗壓彊度,試驗結果錶明隨著再生混凝土塊體替代率的增加,再生混凝土混閤試塊彊度降低。

Broken waste concrete into small blocks, mixing with the nature concrete into the 200*200*200 cube experimental mold , made from recycled concrete mixed blocks, the rate of substitution of recycled con- crete block is 0%, 20% and 30%. Through the cube compressive test, measured compressive strength of con- crete test block under different substitution rate, the results indicated that with increased replacement rate of recycled concrete blocks, try recycled concrete mixing reduced, the strength of the recycled concrete mixed blocks is reduced.
