立即联系/Live ChatNov 26 32 Compressive strength is an effective way of measuring how much load a surface or material can bear The test for this sort of strength is performed by exerting force downward on top of the object paired with an equal and opposite force exerted upward on the bottomThe compressive strength of reinforced test articles reached thanks to this value of the aggregate glass which is used exclusively therein over 30 N/mm2 even 45 N/mm2 and more which corresponds at least to the limiting range between concrete Types I and II and hence to a concrete that is suitable for medium stressed and highly stressed
