大体积砼施工质量监理实施细则.doc

一、质量标准：
（一） 依据标准：
《混凝土结构工程施工及验收规范》(GB50204-92)
《混凝土强度检验评定标准》(BGJ107-87)
《混凝土泵送施工技术规程》(JGJ/T10-95)
（二）基本要求：
1、混凝土所用的水泥、水、骨料、外加剂等必须符合施工规范各有关的规定。
2、混凝土的配合比、原材料计量、搅拌、养护和施工缝处理必须符合施工规范的规定。
3、砼试块的取样、制作、养护和试验必须符合规范要求，其强度必须达到规范标准。
4、对设计不允许有裂缝的结构，严禁出现裂缝，设计允许出现裂缝的结构其裂缝宽度不大于2MM。
5、砼应振捣密实，蜂窝面积、孔洞面积、漏筋长度及施工缝处夹渣层长度必须符合下表规定：
First, quality standards:
(A) based on criteria:
"Construction of Concrete Structures and acceptance" (GB50204-92)
"Concrete Strength Testing Standards" (BGJ107-87)
"Concrete Pumping technical specification" (JGJ/T10-95)
(B) Basic requirements:
1, the cement used in concrete, water, aggregate, admixtures and other construction specifications must meet the relevant requirements.
2, concrete mix, raw materials, measuring, mixing, handling maintenance and construction joints must comply with construction norms.
3, concrete test block sampling, production, maintenance and testing must meet the regulatory requirements, its strength must meet the standard.
4, the design does not allow the structure of cracks, is strictly prohibited cracks, cracks in the structure designed to allow the crack width is not more than 2MM.
5, concrete should be vibrated dense, cellular area, pore size, the length of leakage and construction joints reinforced slag layer length must meet the following requirements:
