This study investigates the self-curing concrete using baby polymer diapers as substitute method of curing process in order to improve mechanical and physical properties of concrete. Three different proportion of baby polymer diapers which are 1%, 3% and 5% were mix with concrete. Slump, compressive strength and drying shrinkage test were performed in order to study the workability, strength and durability of the concrete. All concrete were tested for 1, 3, 7, 14, and 28 days for drying shrinkage test. Meanwhile, all concrete were test at 3, 7 and 28 days for compressive strength test. Compressive strength of concrete containing 5% baby polymer diapers show the highest strength at 28 days compared to others percentage. Thus, it indicates that application of baby polymer diaper as self-cure agent can improve the concrete performances.

Foaming Agent

Lightweight concrete has been used for structural purposes for many years and it is developed very fast in resent years due to its lightweight and favourable for insulation properties. High strength foam concrete is a fairly new kind of lightweight concrete with excellent properties of outstanding workability, low density and high strength. Responsible for these properties are the macro-, meso- and micro- porosity of the foam concrete which are mainly affected by the foaming agent. The influence of foaming agent’s dilution ratio and foam dosage on the fluidity, compressive strength, flexural strength and drying shrinkage of high density foam concrete designed for structural materials is investigated in this paper.
