Cement concrete structure is specified in the technical standard, is characterized by durable level of compression-resistant concrete, and intensity level of pull-resistant concrete, there is unit Mpa, whereas, in the contract drawings, characterized by concrete compression resistant strength Marxist, Marxist and concrete mechanical strength drag There, the unit is daN/cm2.According to the national standards ISO 5574:2012-concrete structures and precast concrete – design standards, are required is the standard to be applied to the design of concrete mixture, this standard uses the material characteristic level of compression resistant strength "concrete" and "resist the pull of the concrete" rather corresponds to the "Moon under compression resistant strength" and "Moon According to the intensity of withstanding the pull ".According to the General conditions of the contract, the terms of the order of 1.5 material, the General conditions of contract and specifications stand in position e is Thursday, and f is the 6th position, g is the drawing (contract)According to the above, the concrete structure was used for the project will be characterized by durable level of compression-resistant concrete and intensity level of pull-resistant concrete, and there is unit Mpa. Thus, the concrete structure of the home guard is currently characterized by concrete compression resistant strength Marxist, Marxist and concrete mechanical strength, have the unit daN/cm2, in drawing contracts, should be replaced by durable level of compression-resistant concrete and intensity level of pull-resistant concrete , and there is unit Mpa.
