An Experimental Study On Structural Concrete Frost-Resistance

摘要

In engineering quality inspection and acceptance and evaluation of structural properties, the quality of structure real object is paid more and more attention to by all parties involved in construction. But the structural detection technology and corresponding rules are lagging. Through the use of the same batch of concrete structure and frost resistance of concrete test block test, the results show that for the same concrete mix, the frost resistance of standard preserved test block is better than that of the core samples drilled from concrete; as for the mixture ratio, the forming and curing conditions are exactly same as the concrete, and the preserved test block frost- resistance performance is also superior to that of concrete core-sample.
