Test Block Layout of the Concrete

The structural concrete strength must be in line with the design requirements. The test pieces shall be used to check the concrete strength of the structural members:Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:Concrete Batching Plants,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc. 100 each mixing 1 plate and no more than 100m3, the same mix of concrete sampling shall not be less than once. 2 the same mix of each working class is not less than one time when the concrete is less than 100. 3 each floor, the same proportion of concrete sampling shall not be less than once. 4 each sample should be at least one set of standard curing test piece, a group of same condition curing specimen. 5 to have the concrete structure which has the resistance to the concrete structure, the concrete test piece should be in the pouring ground random sampling block laying machine, the same project with a concrete sample not less than one time, left a set of standard curing test piece, a group of same condition curing test piece. 600 for the use of d age of 6, the use of +5 age should be noted: the Xiaoyi area during the winter construction mobile ready mixed concrete plant, the daily average temperature of about -5 ready mix concrete plant, and the standard is clear that the -0 and the following is not cumulative, because the concrete strength under this condition, growth is very slow, and age should be controlled at 14d-60d. According to the above requirements, the daily average temperature of 600 degrees D, has more than 60d, therefore, the Xiaoyi area to determine the structure of the construction of the physical strength should be the same condition of the 58d age of the specimen strength as a standard value.
