Limestone machine-made sand concrete modifier and concrete containing limestone machine-made sand concrete modifier
The invention discloses a limestone machine-made sand concrete modifier and concrete containing the limestone machine-made sand concrete modifier. The limestone machine-made sand concrete modifier isprepared from the following raw materials in parts by mass: 5-7 parts of nano colloidal silicon dioxide with the solid content of 15-50% and 4-7 parts of a water repellent agent, wherein the water repellent agent is selected from one of a lotus leaf type water repellent agent and a water-based wax-based water repellent agent. The preparation method comprises the following steps of carrying out fusion stirring according to 5%-7% of the mass of the cement, and uniformly stirring to obtain the novel limestone machine-made sand concrete modifier. According to the limestone machine-made sand concrete modifier, through the secondary hydration reaction, the crystal nucleus effect and the micro-aggregate filling effect of the material, the compressive strength, the breaking strength and the durability of concrete can be improved, and the limestone machine-made sand concrete modifier is simple in preparation process, low in cost and wide in application range.
本发明公开了一种石灰石机制砂混凝土改性剂及含其的混凝土，石灰石机制砂混凝土改性剂，由以下质量份数的原材料制成：固含量为15‑50％的纳米胶体二氧化硅5‑7份、疏水剂4‑7份；所述疏水剂选自荷叶型疏水剂、水性蜡基型疏水剂中的一种，其制备方法按水泥质量的5％‑7％进行融合搅拌，搅拌均匀，即可得到新型石灰石机制砂混凝土改性剂。本发明所述的石灰石机制砂混凝土改性剂，通过其材料的二次水化反应、晶核效应以及微集料填充效应，能提高混凝土的抗压强度、抗折强度以及耐久性，并且制备工艺简单,成本较低，应用范围广泛。
