Abstract
The article reveals the development and analysis of fabric structure for its moisture absorbency property and its application in Civil engineering for curing of concrete. The presence of moisture in concrete and time of curing are the major influencing factors for concrete strength. Normal practice of curing is to wrap the concrete with jute woven fabric and spraying of water. The absorbency characteristics of different GSM (Gram per square meter) of woven and Non-woven fabric were studied. The Non-woven fabric absorbency is superior to woven fabric of same GSM by its three dimensional structure and high pore volume. The strength of concrete cured with Non- woven fabric is 2.1 N/mm2 higher than woven fabric of same 350 GSM. The difference in compressive strength of Non-woven fabric of 350 GSM and 750 GSM is 0.06 N/mm2 which is marginal.
Highlights
With ever increasing demand for absorbent product, textiles are finding application in many areas like Medical, Industrial and so on
Overall the Non-woven structures have retained higher water retaining capacity compared to woven fabric of same GSM
Non-woven materials were found to be overall better in terms of retention of water tested under varying conditions of temperature and RH
Summary
With ever increasing demand for absorbent product, textiles are finding application in many areas like Medical, Industrial and so on. The compressive strength [2] of concrete decreases with increase in temperature, as the evaporation of water takes place at high temperature and results reduction in hydration reaction. If a textile structure can hold more amounts of water and transfer to concrete, the continuous curing process takes place resulting in improvement in concrete strength. The moisture is transmitted into the fabric in two ways, by diffusion of water vapour through the fabric and by wicking of liquid water by capillary transport. This depends on surface property of fibre, total surface area. In contrast to diffusion of water vapour, wicking increases as moisture regain decreases, because the fibre does not absorb the water
