High-strength concrete and preparation process thereof
The invention relates to the field of concrete, and particularly discloses high-strength concrete and a preparation process thereof. The high-strength concrete is prepared from the following components in parts by weight: 460 to 500 parts of cement, 60 to 70 parts of fly ash, 600 to 660 parts of sand, 700 to 800 parts of stone, 10 to 15 parts of a water reducing agent, 100 to 150 parts of water and 320 to 480 parts of resin particles, wherein the tensile strength of the resin particles is not lower than 80 MPa; the preparation method comprises the following steps: mixing the cement, the fly ash, the sand and the stone, and uniformly stirring to obtain a dry mixed material; adding a water reducing agent and water into the dry mixed material, and uniformly stirring and mixing to obtain a wet mixed material; and adding resin particles into the wet-mixed material, and uniformly stirring and mixing to obtain the high-strength concrete. The high-strength concrete is high in compressive strength, low in density, light in self weight and convenient to transport when being applied to concrete prefabricated parts.
本申请涉及混凝土领域，具体公开了一种高强混凝土及其制备工艺。高强混凝土包括以下重量份数的组分：水泥460~500份、粉煤灰60~70份、砂600~660份、石700~800份、减水剂10~15份、水100~150份、树脂颗粒320~480份，所述树脂颗粒的拉伸强度不低于80 MPa；其制备方法为：将水泥、粉煤灰、砂、石混合，搅拌均匀得到干拌料；向干拌料中加入减水剂和水，搅拌混合均匀得到湿拌料；向湿拌料中加入树脂颗粒，搅拌混合均匀得到高强混凝土。本申请的高强混凝土抗压强度高，密度小，自重轻，在应用于混凝土预制件时便于运输。
