Lightweight high-strength foam concrete and preparation method thereof
The invention discloses lightweight high-strength foam concrete and a preparation method thereof, and the lightweight high-strength foam concrete is prepared from the following raw materials in parts by weight: 100 parts of Portland cement, 100 parts of fly ash, 100 parts of expanded perlite, 50 parts of water, 0.6-0.9 part of low-granularity aluminum powder and 0.1-0.5 part of polypropylene fiber. The preparation method comprises the following steps: adding Portland cement, fly ash, expanded perlite and water into a stirrer in parts by weight, stirring for 10-15 minutes, then adding low-granularity aluminum powder and polypropylene fibers in parts by weight, and stirring for 5-10 minutes, thereby obtaining the lightweight high-strength foam concrete. The mixing amount and the particle size of the aluminum powder have influences on the physical and mechanical properties, the anti-freezing property, the heat conductivity coefficient and the pore structure of the foam concrete, the particle size of the aluminum powder and the specific and reasonable dosage of the aluminum powder are controlled, the dry density of the prepared foam concrete block is 800-1100 k/m, and the compressive strength reaches 1020 MPa.
本发明公开了一种轻质高强泡沫混凝土及其制备方法，轻质高强泡沫混凝土，由以下重量份数的原料制备而成：硅酸盐水泥100份、粉煤灰100份、膨胀珍珠岩100份、水50份、低粒度铝粉0.6‑0.9份、聚丙烯纤维0.1‑0.5份。将硅酸盐水泥、粉煤灰、膨胀珍珠岩、水按其重量份加入搅拌机，搅拌10‑15分钟，然后再按其重量份加入低粒度铝粉、聚丙烯纤维搅拌5‑10分钟，制备得到轻质高强泡沫混凝土。本发明铝粉掺量及粒径对泡沫混凝土的物理力学性能、抗冻性能、导热系数和孔结构产生影响，铝粉粒度大小控制及铝粉控制具体合理用量，制备的泡沫混凝土砌块干密度在800‑1100k份/m³,抗压强度达到10〜20MPa。
