喷混凝土的质量控制

Shotcrete Quality Control

影响喷射混凝土质量的因素主要是材料质量和施工工艺。喷射混凝土的原材料包括水泥、砂、石、速凝剂等。控制喷射混凝土的质量必须首先控制原材料的质量。因此,要求水泥必须符合国家标准的规定,并必须有出厂合格证,砂、石的质量必须符合设计要求,谏凝剂等外加剂应符合行业标准,并有产品合格证。

the factors affect the shotcrete quality is mainly materials and construction process of mass. Sprayed concrete materials including cement, sand, stone and SuNingJi etc. Control of sprayed concrete quality must first control the quality of materials. Therefore, the requirement of cement must conform to the state standards, and must have the factory certificate, the quality of sand, stone must comply with the design requirements, the additiveFlocculation agent must conform to the standards and have relevantproduct certificate.
