Cement for cast-in-place piles and preparation method thereof
The invention relates to the technical field of cement, in particular to cement for cast-in-place piles and a preparation method of the cement. The cement for the cast-in-place pile comprises the following components in parts by weight: 40-60 parts of cement clinker, 3-6 parts of desulfurized gypsum, 12-18 parts of superfine ash and 25-35 parts of composite slag micro powder, wherein the compositeslag micro powder comprises the following components in percentage by mass; 75%-85% of slag, 13.5%-24.5% of ceramic waste and 0.5%-1.5% of byproduct anhydrous sodium sulphate; the superfine ash is mainly prepared from the following raw materials in percentage by mass: 65%-80% of ash residues, 18.8%-34.2% of fly ash and 0.8%-1.2% of byproduct anhydrous sodium sulphate. The cement for the cast-in-place piles has excellent breaking strength and compressive strength, and is good in anti-permeability effect and excellent in chemical corrosion resistance.
本发明涉及水泥技术领域，具体而言，涉及一种灌注桩用水泥及其制备方法。一种灌注桩用水泥，包括如下重量份数的组分：水泥熟料40～60份、脱硫石膏3～6份、超细灰12～18份和复合矿渣微粉25～35份；所述复合矿渣微粉包括如下质量百分比的组分；矿渣75％～85％、陶瓷废料13.5％～24.5％和副产元明粉0.5％～1.5％；所述超细灰主要由如下质量百分比的原料制备得到：灰渣65％～80％、粉煤灰18.8％～34.2％和副产元明粉0.8％～1.2％。本发明的灌注桩用水泥具有优异的抗折强度和抗压强度，抗渗效果好，抗化学腐蚀能力优异。
