Anti-cracking and anti-seepage concrete
The invention discloses anti-cracking and anti-seepage concrete, and particularly relates to the field of concrete, the anti-cracking and anti-seepage concrete comprises the following raw materials by weight: 200-300 parts of Portland cement, 780-920 parts of mixed stone, 560-840 parts of filling powder aggregate, 1-1.5 parts of a waterproof sealant, 0.7-1.4 parts of modified fiber, and the balance of water, the mixed stone material is prepared from the following components in percentage by weight: 40 to 50 weight percent of broken stone and 50 to 60 weight percent of broken concrete blocks. On one hand, waste materials can be reused, the building construction cost can be reduced, water soaking operation is conducted before use, on the other hand, the water absorption capacity of glass and mica is weaker than that of sand, the thermal expansion coefficient of glass and mica is small, and therefore the situation that a concrete body cracks due to shrinkage is effectively avoided; the modified fibers are added, and the flaky monomers are extremely easily dispersed into fiber monofilaments under the action of soaking of water and friction force of a stirrer, so that the anti-cracking effect is achieved, and the mechanical property, freeze-thaw resistance and impermeability of the concrete are further effectively improved.
本发明公开了一种防裂抗渗混凝土，具体涉及混凝土领域，其中包括以下重量份数的原料：硅酸盐水泥200‑300份、混合石料780‑920份、填充粉骨料560‑840份、防水密封剂1‑1.5份、改性纤维0.7‑1.4份，其余量设置为水，所述混合石料按重量百分比计包括碎石40wt%‑50wt%和破碎混凝土块50wt%‑60wt%。本发明一方面能够对废材的重新利用，降低建筑施工的成本，且在使用前均进行浸水操作，另一方面玻璃和云母的吸水能力较砂而言较弱，且自身的热膨胀系数小，从而有效避免因提及收缩引发的混凝土主体的开裂情况的发生；添加改性纤维，片状单体在水的浸泡和搅拌机摩擦力的作用下，极易分散为纤维单丝，从而起到抗裂效果，且进一步有效提高混凝土的力学性能抗冻融性及抗渗性。
