Unfired concrete terrace material
The invention discloses an unfired concrete terrace material which comprises the following raw materials in parts by weight: 400-500 parts of silicate 425 cement, 50-100 parts of first-grade coal ash,20-40 parts of a UEA expanding agent, 700-950 parts of unfired fine aggregate sand, 900-1200 parts of unfired coarse aggregate stone, 0.5-1.6 parts of an additive and 160-200 parts of water. The non-flammable concrete terrace material disclosed by the invention can ensure that sparks are not generated, the surface is smooth, wear-resistant and dust-free, and the strength and the construction performance are good during grinding wheel friction and metal collision,meanwhile, on the basis that the strength and the construction performance are met, it can be guaranteed that early plastic crackingand later shrinkage cracking of the material do not occur, and the terrace construction requirement is met.
本发明公开了一种不发火混凝土地坪材料，按重量份数计原料包括：硅酸盐425水泥400‑500份、一级粉煤灰50‑100份、UEA膨胀剂20‑40份、不发火细骨料砂700‑950份、不发火粗骨料石900‑1200份、外加剂0.5‑1.6份、水160‑200份。本发明的不发火混凝土地坪材料在砂轮摩擦以及金属碰撞时，可以保证不产生火花，表面平整耐磨不起尘，强度和施工性能好；同时在满足强度和施工性能的基础上，可以保证材料不出现早期塑性开裂和后期收缩开裂，满足地坪施工要求。
