Measures to control shrinkage cracks: In structural concrete shrinkage cracks are controlled by using temperature reinforcement. So, how does Porotherm ensure crack free walls? Checking the sulfate content of bricks used in construction, The damping of brick wall has to avoided, as these are more prone to sulfate attack when it is damp. When the water used is too much, it causes the concrete to shrink. When the specifications in this design are not met or not properly designed, then such errors eventually lead to cracks in the buildings. At low-stress levels, it is believed to be due to seepage and viscous flow and at high-stress levels, it can be due to microcracking and inter-crystalline slip. masterclass session peter andrews october 2009. outline (1). the permeability of the concrete is a straight function of the interconnection and porosity of pores of the cement paste. 8$r_|!- The proportion of fine aggregate (silt, clay, dust) in the aggregate should not exceed 3%. professor cynthia ford the university of montana school of, EU Procurement and Remedies Changes - .
