Question

A concrete masonry unit is tested for compressive strength and produces the following results: Failure load = 100000 lb Gross area = 170 in2 Gross volume = 960 in3 Net volume = 836 in3 Please round to the nearest hundredth (i.e., 0.01). 1. What is the percentage of net cross-sectional area? = Answer % 2. Is the unit categorized as solid or hollow? Write down either solid or hollow. No spaces, and case is unimportant. Answer 3. What is the net area? = Answer in2 4. What is the net area compressive strength? = Answer psi 5. Does the compressive strength satisfy the ASTM requirements for load bearing units? Write down either yes or no. No spaces, and case is unimportant. Answer
