Description

一种高性能水泥
技术领域
本发明涉及建筑材料技术领域，具体涉及一种早强高性能水泥。
背景技术
水泥，是粉状水硬性无机胶凝材料，其加水搅拌后成浆体，能在空气中硬化或者在水中更好的硬化，并能把砂、石等材料牢固地胶结在一起，广泛应用于土木建筑、水利、国防等工程。硫铝盐酸水泥是一种高效特种水泥，具有高性能，早强，高强，低碱性，耐腐蚀等特点，但也存在早起水化热高，凝结时间果断，后期强度有不同程度的倒缩等问题。
发明内容
本发明的目的是提供一种硫铝盐酸水泥，以解决硫铝酸盐水泥存在的问题。
一种高性能水泥，由以下原料按照重量百分比组成：石膏2％，硼砂0.5％，矿物掺合料15％，硫铝盐酸水泥82.5％；
所述矿物掺合料由以下组份组成：花岗岩石粉8重量份；天然砂60重量份，水泥熟料20重量份，硅灰15重量份，石灰石粉15重量份，粉煤灰15重量份。
本发明有益效果：
本发明能有效提高水泥的抗压强度和早期强度，同时充分利用了工业废渣，大大降低了生产成本，有效改善硫铝盐酸水泥的性能。
具体实施方式
实施例1
一种高性能水泥，由以下原料按照重量百分比组成：石膏2％，硼砂0.5％，矿物掺合料15％，硫铝盐酸水泥82.5％；
