Thermal Conductivity of foamed concrete
A systematic study of the thermal conductivity of foamed concrete for assorted values of (i) foam content (25%, 50% and 70 %), (ii) water-cement ratio (0.35- 0.55) and (iii) polymer content (5 to 20 % of cementitious material weight) is presented. Experiments were done using a heat flow meter …

Foamed concrete for improved local trench reinstatements
… construction products in today's business world, concrete and concrete products can be made to meet exacting standards and new designs. Foamed concrete is not a new material having found extensive use in Europe and other parts of the world, however, its use in Malta is totally new.

Development of foamed concrete : enabling and supporting design
Foamed concrete has considerable potential as a material for use in the construction industry. However, although some researches have been conducted on the characteristics of foamed concrete, thus far, knowledge on the behaviour of foamed concrete has been limited. Hence, predictions of the …

Experimental study of fracture energy for foamed concrete
Foamed concrete has recently gained attention as an alternative material to normal concrete in structural engineering. As a structural component, foamed concrete has many advantages given its characteristics such as high strength with low density, good serviceability, and lightweight. Therefore, …

Impact resistance of foamed concrete slab and its modifications subjected to hemispherical impactor
… simulation. The three methods employed slabs of foamed concrete and its modifications. The modifications of foamed concrete included foamed concrete substituting sand with Rice Husk Ash (RHA) and foamed concrete reinforced by Polypropylene fibre (PF). Experimental work produced properties data of …

Sequestration of carbon dioxide (CO2) using bio-foamed concrete brick incorporating bacillus tequilensis bacteria
… biological approach to sequestrate CO2 in bio-foamed concrete bricks (B-FCB). The used of biological approach in B-FCB is considered as new direction of CO2 sequestration which in role helps to reduce the amount of CO2 from atmospheric at the same time improve the strength and physical …

The effect of high volumes of ungraded fly ash on the properties of foamed concrete
Foamed concrete is produced by combining foam and slurry thus entrapping numerous small bubbles of air in the cement paste or mortar. The density of foamed concrete is a function of the volume of foam added to the slurry and the strength decreases with decreasing density. In this study the effect …

Investigation of green foamed concrete incorporating palm oil fuel ash and eggshell ash as partial cement replacement
The tendency of concrete to absorb heat, high thermal conductivity and self-weight due to its high density, and its extensive use has given rise to Urban Heat Island (UHI). Therefore, this study was carried out to provide a solution to these limitations by developing innovative lightweight green …

Microstructure characterization of foamed cement and concrete
Freeze-thaw deterioration of concrete is a major durability issue in cold climates. Air-entraining admixtures are used to create a network of fine bubbles that enhance frost resistance. Experience has shown that fresh air content alone cannot predict the effectiveness of the entrained air system. …
