Experimental study on anti-freezing and thawing of preparation of wet mixed mortar with full component recycled sand in plastering engineering

The experiments of concrete in seawater under 0, 25, 50, 75 and 100 freezing-thawing cycles were performed using fast freezing and thawing method. Appling large concrete static and dynamic triaxial test system, the influence of freezing and thawing cycles on compressive strength and strain at peak stress point of concrete in seawater were detected, and then simple mathematical expressions were established.

Mixed Mortar

This paper concerns the use of recycled fine concrete and clay brick aggregates to respectively globally replace natural fine aggregates (sand) in the production of mixed mortar. The fundamental properties such as the compressive strength and the shrinkage ratio of mixed mortar made of the recycled fine aggregates are tested and discussed in detail. The experimental results indicated that it is viable to produce mixed mortar using recycled fine concrete and clay brick aggregates, the compressive strength of mixed mortar made of recycled fine aggregates is lower than that of mixed mortar made of natural fine aggregates and the shrinkage ratio of mixed mortar made of recycled fine aggregates is larger, cured in natural environment.

Freezing And Thawing Cycles

As a result of the experimental study, there was estimated the variability of the form of complete diagrams σ-ε of concrete under uniaxial compression. It is shown that the coefficients of variation of concrete deformation characteristics are comparable with the coefficient of variation of strength within one concrete class in terms of compressive strength. It was found out that the effect of freezing and thawing cycles leads not only to a decrease in the compressive strength of concrete, but also to a decrease in the ultimate deformations and the initial modulus of elasticity. Thus, when using diagram methods for calculating reinforced concrete structures, it is necessary to take into account the influence of variability not only in the strength, but also in the deformation characteristics of concrete.
