Self-compacting concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to self-compacting concrete and a preparation method thereof. The self-compacting concrete is prepared from 340-365 parts of Portland cement; 190 to 210 parts of water; 820 to 835 parts of waste concrete block coarse aggregate; 850 to 875 parts of waste organic glass fine aggregate; 90 to 110 parts of fly ash; 75 to 80 parts of slag powder; 7.3 to 8.0 parts of a water reducing agent; 0.8 to 1.2 parts of polypropylene fiber; 2.1 to 3.0 parts of an ester surfactant. The self-compacting concrete can be used for various components of buildings, and has the advantages that compared with common self-compacting concrete, the fluidity, the compressive strength and the splitting tensile strength are obviously improved, and thedefect that the compressive strength and the tensile strength of the concrete are weakened when organic glass replaces fine aggregate to be used for coagulation is overcome.
本发明涉及混凝土的技术领域，更具体地说，它涉及一种自密实混凝土及其制备方法，其中，自密实混凝土包括硅酸盐水泥340‑365份；水190‑210份；废混凝土块粗骨料820‑835份；废有机玻璃细骨料850‑875份；粉煤灰90‑110份；矿渣粉75‑80份；减水剂7.3‑8.0份；聚丙烯纤维0.8‑1.2份；酯类表面活性剂2.1‑3.0份；本发明的自密实混凝土可用于建筑物的各种构件，其具有相较于普通自密实混凝土，流动性、抗压强度和劈裂抗拉强度均明显提升，且克服了将有机玻璃代替细骨料用于混凝时，造成混凝土抗压、抗拉强度减弱的优点。
