Concrete with high pressure resistance and preparation method thereof
The invention provides concrete with high pressure resistance and a preparation method thereof, and relates to the technical field of building materials. The invention discloses concrete with high pressure resistance. Comprising the following raw materials in parts by weight: 150 to 180 parts of Portland cement, 12 to 17 parts of silicon powder, 100 to 140 parts of quartz powder, 130 to 145 parts of quartz sand I, 115 to 125 parts of quartz sand II, 110 to 135 parts of water, 17 to 22 parts of binder, 5 to 12 parts of water repellent agent, 160 to 260 parts of stone I, 130 to 140 parts of stone II, 140 to 150 parts of stone III, 110 to 130 parts of steel fiber, 50 to 70 parts of nano silicon dioxide, 32 to 52 parts of sodium carboxymethyl cellulose, 5 to 10 parts of 4A zeolite and 20 to 40 parts of magnesium stearate. 10-30 parts of talcum powder, 10-20 parts of lauryl sodium sulfate and 5-8 parts of a modifier. The steel fiber is modified by the modifier, passes through the mixture B and then is mixed with the mixture A, so that the bonding strength of each component is improved, the structure fineness is increased, the working performance of the concrete is further improved, and the durability, the bearing capacity and the compressive strength of the concrete are improved.
本发明提供一种抗压能力强的混凝土及其制备方法，涉及建筑材料技术领域。该抗压能力强的混凝土，包括以下重量份的原料：硅酸盐水泥150‑180份、硅粉12‑17份、石英粉100‑140份、石英砂一130‑145份、石英砂二115‑125份、水110‑135份、粘结剂17‑22份、疏水剂5‑12份、石子一160‑260份、石子二130‑140份、石子三140‑150份、钢纤维110‑130份、纳米二氧化硅50‑70份、羧甲基纤维素钠32‑52份、4A沸石5‑10份、硬脂酸镁20‑40份、滑石粉10‑30份、十二烷基硫酸钠10‑20份、改性剂5‑8份。通过将钢纤维进行改性剂改性，通过混合料B后与混合料A混合，提高了各组分的黏结强度，增加了组织细密度，进而改善混凝土的工作性能，提升混凝土的耐久性、承载力、抗压强度。
