promotion of clinker concrete

January 24, 2019 by zzgl5656  

For example, the resistance of concrete carbonation, generally the carbonation depth of concrete structures to represent. The relative carbonation depth is smaller, said anti carbonization ability, clinker concrete carbonation coefficient is less than 1, which indicated the effects of clinker on concrete carbonation contribution. Of course, in order to facilitate the clear analysis of clinker grinding unit cost of gain and loss, conversion efficiency parameters can also be unified concept, but it is necessary to make the appropriate instructions, so as to avoid misunderstanding.

In the composite technology using the clinker and superplasticizer and other chemical additives or other mineral powder (referred to as the double doped Technology), to use the efficiency parameters of composite effect. This situation often encountered in practical engineering, without the general analysis, however when the efficiency evaluation, to be considered.

In the current promotion of clinker concrete in new technology, the general is the use of clinker concrete and cement concrete as reference, efficiency evaluation of clinker grinding unit costs remain equal work and 28d compressive strength conditions. But for some concrete engineering or special performance requirements of the clinker concrete, can not fully considered the work and 28d strength requirements.
