Resulted in a Ca/Si ratio of 1.26 and Al/Si ratio of 0.11. A high calcium-silicate content was found in the concrete which SEM analysis that there was a good bond between the palm kernel shells and the It differentiates between hardened concrete in the following states: 1) as-received 2. lightweight, normal-weight and heavy-weight concrete. This document specifies a method for determining the density of hardened concrete.

PKS concrete specimens at 28-day of curing was 2.85 MPa which was also 3.2% toĥ7.07% better than the other PKS sizes concrete. BS EN 12390-7 -2019 pdf free download.Testing hardened concrete Part 7: Density of hardened concrete. The compressive strength of the 12 mm PKSĬoncrete specimens at 28-day of curing was 10.2 MPa which was 4% to 15.9%īetter than the other PKS sizes concrete.
Which implies that the PKS concrete satisfied the requirement of lightweightĬoncrete for structural application. That the densities of the concrete specimens were all less than 2000 kg/m3, The tests performed on the concrete are dryĭensity, compressive strength, flexural strength, EDS and SEM. RPK sizes were used to replace coarse aggregate in the concrete andĬured for 7, 14, 21 and 28 days. Sizes of PKS of 6, 8, 10, 12 mm and mix (consisting of 25% each of the four To investigate the properties of lightweight concrete produced with different Is desirable to promote sustainable development.
