Influence of foaming agent type on the behavior of foamed concrete

الملخص EN

In this work the desired aim is to study the effect of two various sorts of afoaming agents on the properties of foamed concrete to obtain high qualitywith a target density is nearly 1600 kg/m3.

The standard samples weredesigned by employing two types of foam agent (FA), the first one iscommercially named (ESOC foam agent, FA) while the second is thefoam of detergent liquid (D) which known (Fairy).

The results showed thatthe FA sample records the lower bulk density compared to the other types.

The perfect mix which involved 1wt.

% of (D) had higher values of thecompressive strength 20.25MPa, 16.32MPa of the curing in water and airrespectively and flexural strength (F.

S) values were 6.89MPa, 4.47MPa ofthe cured samples in (air, water) for various durations (7, 14 and 28) dayscompared to the samples that contained 1and 0.8wt.

Theobtained compressive strengths were 5.1MPa, 4.3MPa while the flexuralstrengths were 2.74MPa, 2.9MPa for the samples contained 1wt.

It isobvious that the addition of foam to the cement mortar paste imparts greatcharacteristics as lightweight with flowability.

These properties and othersmake it suitable for some applications, for example, a decrease of the deadload from the structure, thermal and acoustic insulating and use it in nonstructural sections such as a In this work the desired aim is to study the effect of two various sorts of afoaming agents on the properties of foamed concrete to obtain high qualitywith a target density is nearly 1600 kg/m3.
