Extract of Biomaterial as Admixture for Internal Curing Agent for Concrete

The demand for concrete in the construction sector is growing gradually due to its strength and durability. Concrete's interior relative humidity influences its strength and longevity. In the process of internal curing concrete along with the surface moisture, extra internal moisture is provided so that self-desiccation or dehydration can be avoided. In this paper, biomaterial extract is used to examine the performance of internally cured concrete and is compared with the performance of air-cured and conventionally cured concrete. The dosages of biomaterial extract used as internal curing agents are 0.0 %, 0.20 %, 0.40 %, 0.60 %, 0.80 %, and 1.0 % by weight of cement. This manuscript focuses on the compressive power of M-20 grade concrete and using Biomaterial extract as an internal curing agent determined for 3, 7, and 28 days and compared with air-cured and traditional cured cement concrete respectively. From the experimental test results and observations, the compressive potency of M-20 grade tangible enhances with a boost in dosages of extract of biomaterial up to 0.60% by weight of cement, if the dosage increased more than 0.60 % compressive strength decreases. The results are optimistic in bio-self-cured concrete which is environmentally friendly and low-cost and also improves the level of hydration.
