Axial Compressive Strength of Foamcrete with Different Profiles and Dimensions
Lightweight foamcrete is a versatile material; primarily consist of a cement based mortar mixed with at least 20% volume of air. High flow ability, lower self-weight, minimal requirement of aggregate, controlled low strength and good thermal insulation properties are a few characteristics of foam...

description |
Lightweight foamcrete is a versatile material; primarily consist of a cement
based mortar mixed with at least 20% volume of air. High flow ability, lower self-weight,
minimal requirement of aggregate, controlled low strength and good thermal insulation
properties are a few characteristics of foamcrete. Its dry densities, typically, is below 1600
kg/m3 with compressive strengths maximum of 15MPa. The ASTM standard provision
specifies a correction factor for concrete strengths of between 14 and 42MPa to
compensate for the reduced strength when the aspect height-to-diameter ratio of specimen
is less than 2.0, while the CEB-FIP provision specifically mentions the ratio of 150 x 300
mm cylinder strength to 150 mm cube strength. However, both provisions requirements
do not specifically clarify the applicability and/or modification of the correction factors
for the compressive strength of foamcrete. This proposed laboratory work is intended to
study the effect of different dimensions and profiles on the axial compressive strength of
concrete. Specimens of various dimensions and profiles are cast with square and circular
cross-sections i.e., cubes, prisms and cylinders, and to investigate their behavior in
compression strength at 7 and 28 days. Hypothetically, compressive strength will decrease
with the increase of concrete specimen dimension and concrete specimen with cube
profile would yield comparable compressive strength to cylinder (100 x 100 x 100mm
cube to 100dia x 200mm cylinder). |
