In this work the desired aim is to study the effect of two various sorts of a foaming agents on the properties of foamed concrete to obtain high quality with a target density is nearly 1600 kg/m3. The standard samples were designed by employing two types of foam agent (FA), the first one is commercially named (EABSSOC foam agent, FA) while the second is the foam of detergent liquid (D) which known (Fairy). The results showed that the FA sample records the lower bulk density compared to the other types. The perfect mix which involved 1wt.% of (D) had higher values of the compressive strength 20.25MPa, 16.32MPa of the curing in water and air respectively and flexural strength (F.S) values were 6.89MPa,4.47MPa of the cured samples in (air, water) for various durations (7,14 and 28) days compared to the samples that contained 1and 0.8wt. % of FA. The obtained compressive strengths were 5.1MPa, 4.3MPa while the flexural strengths were 2.74MPa, 2.9MPa for the samples contained 1wt. %foam agent (FA) after the curing into water and air at the same duration. It is obvious that the addition of foam to the cement mortar paste imparts great characteristics as lightweight with flowability. These properties and others make it suitable for some applications, for example, a decrease of the dead load from the structure, thermal and acoustic insulating and use it in non-structural sections such as a wall.
