C30 super-thick floor slab concrete and preparation method thereof
The invention relates to the technical field of floor slab concrete, in particular to C30 super-thick floor slab concrete. The thickness of the C30 super-thick floor slab concrete is larger than 1m. The C30 super-thick floor slab concrete is prepared from, by mass, 164-166 parts of water, 270-310 parts of cement, 60-85 parts of grade-I coal ash, 700-850 parts of sand, 1050-1080 parts of broken stone, 5-7 parts of a water reducing agent and 30-34 parts of an anti-cracking agent. According to the invention, through reasonable proportioning of the raw materials, hydration heat generated by the poured concrete is relatively low, the temperature difference between the interior and the exterior of the C30 super-thick floor slab concrete is small, and the possibility of cracks generated by the super-thick floor slab concrete is reduced; and meanwhile, the anti-cracking agent is added, so that the possibility that the super-thick floor slab concrete cracks is further reduced, the prepared C30 super-thick floor slab concrete has the advantages of high strength and high resistance, the durability, the bearing capacity and the service life of the C30 super-thick floor slab concrete are all improved, and the use safety of a concrete building is improved.
本发明楼板混凝土技术领域，尤其是一种C30超厚型楼板混凝土，所述C30超厚型楼板混凝土的厚度大于1m，按质量份数计，包括的原材料为：水164‑166份、水泥270‑310份、Ⅰ级粉煤灰60‑85份、砂700‑850份、碎石1050‑1080份、减水剂5‑7份、抗裂剂30‑34份；本发明通过合理的原材料配比，使得浇筑后的混凝土产生的水化热较低，C30超厚型楼板混凝土的内部与外部的温差小，降低了超厚型楼板混凝土产生裂缝的可能性；同时添加了抗裂剂，抗裂剂也进一步降低了超厚型楼板混凝土产生裂缝的可能性，使得制备出的C30超厚型楼板混凝土具备高强度、高抗性的优点，其耐久性、承载力和使用寿命均得到提高，提高混凝土建筑的使用安全性。
