compressive strength vs concrete density correlation

Jun 30, 2020 The compressive strength was in the range of 0.4–6.0 MPa after 28 days with a density range of 471–1212 kg/m 3. The reduction of compressive strength was due to the increased pores generated by the decomposition of H 2 O 2. The pores acted as the stress concentration point and prone to failure when load is applied. Read More
