Concrete grouting material ratio in water conservancy engineering - the importance of control Concrete grouting material manufacturer

grouting grouting grouting material manufacturer price CGM high-strength non-shrinkage grouting material factory, the mix proportioning of the concrete grouting material in water conservancy engineering and grouting material manufacturer to reveal to you! Various concrete grouting material mix proportion of different types of structures must be selected through the experiment, the test method shall be carried out according to the relevant provisions of the sd45-82. Concrete grouting material mixture ratio 7 days before the test, the contractor shall present the various ingredients and mixture ratio test mixing, molding and curing of mixture ratio test plan submitted to the supervisor. The mix proportion design of concrete grouting materials and grouting material manufacturers provide! （ 1) Contractor according to the requirement of the construction drawings and engineering characteristics of concrete grouting material, determine the various raw materials, should be under the condition of supervision engineer to witness, on-site sampling of raw materials, to witness and fill in the record, to have appropriate level of qualification of laboratory for mix proportion design of concrete grouting material and try to match. Supervision engineer in examination and issued by the laboratory concrete grouting material and the corresponding single of the concrete grouting material performance, can meet the engineering requirements, shall be allowed for mixing and casting of concrete grouting material work. （ 2) Hydraulic concrete grouting material water cement ratio of the larger value shall comply with the provisions of the table 2. （ 3) Slump of concrete grouting material, should be based on the structure of the nature and content of steel and concrete grouting material transportation, casting methods and c60 grouting material price climate condition, as far as possible use small slump, hydraulic plain concrete grouting or less concrete grouting material of slump, generally between 3 ~ 5 cm, reinforcement ratio is less than 1% of the reinforced concrete grouting material slump in between 5 to 7 cm, reinforcement ratio of more than 1% of the reinforced concrete grouting material slump between 7 ~ 9 cm. Concrete grouting material mixture ratio adjustment: concrete mixture ratio should be selected by the contractor through field investigation and test, in the process of construction, the contractor needs to change approved by the supervisor without shrinkage of yunnan epoxy grouting material of the mix proportioning of the concrete grouting material and must be approved by supervisor. When the contractor use client provides the concrete mixture ratio should be the second interview, does not exempt from the quality responsibility of contractor.
