Study on compressive strength test and discussion on its influencing factors of autoclaved aerated concrete blocks using penetration resistance method
In response to the issues of sample destruction,cumbersome testing procedures,and low testing effi-ciency in the compressive strength testing of autoclaved aerated concrete blocks,research has been conducted on the penetration resistance method for testing the compressive strength of autoclaved aerated concrete blocks,and related influencing factors have been discussed. The results indicate that different types of penetra-tion equipment have negligible effect on the penetration depth results;choosing the horizontal penetration method can avoid the influence of inertial gravity on the penetration depth;the porous structural characteris-tics of the block result in its surface moisture content being significantly lower than the internal moisture con-tent;when the surface moisture content of the block is less than 15％,the penetration depth remains basically stable;there is a linear relationship between the penetration depth and the compressive strength of the block .
