Cement-based concrete plate adopting low-alkalinity cement and preparation method of cement-based concrete plate
The invention discloses a cement-based concrete plate adopting low-alkalinity cement and a preparation method of the cement-based concrete plate. The cement-based concrete plate comprises the raw materials in parts by weight: 100-200 parts of low-alkalinity cement, 80-140 parts of fused quartz, 50-200 parts of common quartz and 20-60 parts of water. The preparation method of the cement-based concrete plate adopting the low-alkalinity cement comprises the following steps: (1) uniformly mixing the raw materials according to the formula ratio to form slurry; (2) pouring the slurry into a mold, curing, and demolding to obtain a concrete slab; (3) carrying out autoclaved curing; and (4) curing the concrete slab for 2 days to obtain a molded product. The fused quartz not only can improve the early strength of the plate, but also serves as a framework of concrete and has a function of improving the later strength. The use of low-alkalinity cement avoids the efflorescence phenomenon on the surface of the plate. The fused quartz concrete slurry has no corrosion effect on the metal part, and the metal part can have long service life.
本发明公开了一种采用低碱度水泥的水泥基混凝土板材及其制备方法，包括以重量份计的原料：低碱度水泥100‑200份、熔融石英80‑140份、普通石英50‑200份和水20‑60份。上所述的采用低碱度水泥的水泥基混凝土板材的制备方法，包括以下步骤：(1)按配方量将各原料混合均匀成为浆料；(2)将浆料倒入模具中，养护后脱模，得到混凝土板；(3)蒸压养护；(4)将混凝土板养护2天，得到成型品。熔融石英不仅可提高板材的早期强度，还充当混凝土的骨架和对后期强度有提升作用。低碱度水泥的使用避免板材表面泛碱现象。熔融石英的混凝土浆料对金属件没有腐蚀作用，金属件能有较长的使用寿命。
