在混凝土中掺加高效减水剂,在一般施工及养护条件下。可制成高强混凝土。现将这种高强混凝土的配制与应用情况叙述如下。一、高强混凝土的特性及应用1.高强混凝土的性质该混凝土的抗弯强度是抗压强度的1/10,抗拉强度是抗压强度的1/16。弹性模量为3.7×10~(?)~4.3×10~(?)N/cm~3。握裹强度、抗压强度,冲击强度与普通混凝土大致相等。而高强混凝土的极限变形只有0.3%。该混凝土的收缩、徐变比普通混凝土小。
Adding high-efficiency water-reducing agent in concrete under general construction and curing conditions. Can be made of high-strength concrete. The formulation and application of such high-strength concrete are described below. First, the characteristics and application of high-strength concrete 1. High-strength concrete properties The concrete’s bending strength is 1/10 of the compressive strength, tensile strength is 1/16 of the compressive strength. The elastic modulus is 3.7×10~(4.3)~4.3*10~(?)N/cm~3. The grip strength, compressive strength, and impact strength are approximately equal to those of ordinary concrete. The ultimate deformation of high-strength concrete is only 0.3%. The shrinkage and creep of the concrete is smaller than ordinary concrete.
