Coral sand concrete and preparation method thereof
The invention relates to glass fiber coral sand concrete and a preparation method thereof. The glass fiber coral sand concrete is prepared from the following components in parts by mass: 650 to 655 parts of cement, 18 to 36 parts of nano calcium carbonate, 100 to 102 parts of fly ash, 100 to 102 parts of quartz powder, 218 to 220 parts of silica fume, 1060 to 1065 parts of coral sand, 243 to 245 parts of seawater, 6.7 to 7 parts of polycarboxylate superplasticizer and 18 to 36 parts of glass fiber. The elasticity modulus of the glass fiber is 70-80 GPa, the nominal length is 6-12 mm, the density is 2.4-2.7 g/cm < 3 >, the breaking strength is 400-600 Mpa, and the melting point is 680 DEG C. The preparation method comprises the following steps: firstly, preparing a cementing material, then preparing gelatinous slurry, then adding glass fibers, dispersing to obtain a concrete material, and finally, pouring and curing the concrete material to obtain the required glass fiber coral sand concrete. The strength, stability and durability of the coral sand concrete can be improved, and the service life of the coral sand concrete is effectively prolonged.
本发明涉及一种玻璃纤维珊瑚砂混凝土及其制备方法，玻璃纤维珊瑚砂混凝土成分按照质量份数计包括水泥650‑655份，纳米碳酸钙18‑36份，粉煤灰100‑102份，石英粉100‑102份，硅灰218‑220，珊瑚砂1060‑1065份，海水243‑245份，聚羧酸减水剂6.7‑7份和玻璃纤维18‑36份；所述玻璃纤维的弹性模量为70‑80GPa，公称长度为6‑12mm，密度为2.4‑2.7g/cm3，断裂强度400‑600Mpa，熔点680℃。所述制备方法中，首先制备胶凝材料，然后制备胶凝状浆体，接着加入玻璃纤维分散后得到混凝土材料，最后混凝土材料浇筑、养护后得到所需的玻璃纤维珊瑚砂混凝土。本发明可以提高珊瑚砂混凝土强度、稳定性以及耐久性，有效提高珊瑚砂混凝土的使用寿命。
