目前,高强混凝土在我国已经实用化。建设部已经将高强混凝土作为新技术项目在全国推广。高强混凝土的基本特点是强度高、在施工阶段强度增长速度快、抗腐蚀能力强、节约材料等。但是,目前施工现场确认结构混凝土强度质量的无损检测技术只能适用于50MPa以下强度的混凝土
At present, high-strength concrete has been practically used in our country. The Ministry of Construction has promoted high-strength concrete as a new technology project throughout the country. The basic characteristics of high-strength concrete are high strength, rapid strength growth during construction, strong corrosion resistance, and material conservation. However, the nondestructive testing technology currently used to confirm the structural concrete strength at the construction site can only be applied to concrete with a strength of less than 50 MPa.
