Hace 2 días · 3.2. Effect of air pores and capillary pores on compressive strength. The amount of water in concrete plays a crucial role in determining the ratio of capillary pores to cementing materials. As the water-to-cement ratio rises, there is an increase in capillary pores, leading to a reduction in the CS of the concrete (de Larrard, Citation 1999 ...
