31. Mortars used in this technique typically have a compressive strength ranging from at least 400 ANSI testing procedures. 32. Otherwise, check out compressive strength . 33. In a comprehensive research program, Abrams established the relationship between the water-cement ratio and the compressive strength of concrete. 34. Excessive compaction of pervious concrete results in higher compressive strength , but lower porosity ( and thus lower permeability ). 35. Some foams are even stronger, with compressive strengths of 50 psi and 100 psi in a free rise state. 36. In the case of bridges or offshore structure, compressive strength or upward flexural strength may be of more interest. 37. The compressive strength of the material would correspond to the stress at the red point shown on the curve. 38. This was largely due to the ease of use of Portland cement, its quick setting, and high compressive strength . 39. In general increasing the CaO content of the slag results in raised slag basicity and an increase in compressive strength . 40. Bamboo has a higher specific compressive strength than wood, brick, or concrete and a specific tensile strength that rivals steel.
