According to the calculation method for cement proportioning [31], the design strength of CPC 42.5 with crushed stone admixture should meet the standard of C30 in a cyclic moist-dry environment, so the calculated water-cement ratio is 0.6, as shown in empirical equation (2). Considering the water absorption capacity of mudstone …

Experiments conducted by Zhang et al. revealed that for concrete with a water–cement ratio of 0.32, the optimal stone powder content is 10%. In the case of concrete with a water–cement ratio of 0.45, the optimal stone powder content should not exceed 20%, as this level results in peak seepage resistance.

Lay down half of your medium-sized gravel -- enough for 2 or 3 inches -- to start your base. Walk on it, wearing heavy boots, to compact it. Add the final layer of gravel and compact that layer too. Next, add 1 inch of coarse construction sand and compact it. Then "fluff" the very top of the sand layer with a light leaf rake, to create a ...
Root Pruning. One of the key strategies for addressing concrete damage caused by tree roots is root pruning. Root pruning is a method used to manage and redirect the growth of tree roots that threaten to compromise the integrity of nearby concrete structures. Below is the step-by-step process of how to do it:
Carbonation-induced corrosion often occurs on building facades with shallow concrete cover. (70157) Carbonation of concrete also lowers the amount of chloride ions needed to promote corrosion. In new concrete with a pH of 12 to 13, about 7,000 to 8,000 ppm of chlorides are required to start corrosion of embedded steel.
