Proportioning method of high-temperature-resistant material for fireplace
The invention discloses a proportioning method of a high-temperature-resistant material for a fireplace, the high-temperature-resistant material for the fireplace is prepared from the following components: cement, an admixture, coarse aggregate, an additive and polypropylene fiber, and the actual addition amount of each component is calculated according to the area of the built fireplace. The refractory castable has the advantages of high erosion resistance, high temperature sudden change resistance, high thermal stress damage resistance, high thermal shock resistance or high thermal spalling resistance, high compactness, low porosity and high permeability resistance; the additive is adopted, so that the water consumption is reduced, and the problems that the surface of concrete is loose and peeled off and the strength is reduced due to the fact that redundant water usually exists as free water or capillary pore water are solved; the vibration screening equipment is used for screening, so that the mix proportion is ensured, the compactness of the concrete is improved, and the workability of the concrete can be improved; the expansion pressure in the heating process is released by adding the polypropylene fibers, so that the crack resistance is improved, and the high-temperature resistance of the concrete is improved.
本发明公开了一种壁炉用的耐高温材料的配比方法,包括以下组分制成：水泥、掺和料、粗骨料、外加剂和聚丙烯纤维，根据砌壁炉面积计算出各组分的实际加量，本申请中的壁炉用的混凝土耐高温性好，有较强的抗侵蚀能力和耐温度急变的能力，抵抗热应力的损坏，具有耐急冷急热的抗热震性或抗热剥落性，具有较高的致密性、气孔率低、抗渗透性强的特点；通过采用外加剂从而减少水用量，防止多余的水通常以自由水或者毛细孔水存在，导致混凝土表面酥松剥落现象，强度下降的问题；通过振动筛分设备进行筛分，保证配合比，提高混凝土的密实度，还可以提高混凝土和易性；通过添加聚丙烯纤维释放受热过程中的膨胀压力提高抗裂性能，提高混凝土的耐高温性能。
