Early-age hydration and shrinkage of cement paste with coir fibers as studied by Nuclear Magnetic Resonance

Nuclear Magnetic Resonance (NMR) is used to study the early-age hydration as well autogenous shrinkage and drying of cement paste with addition coir fibers. The dosage water content fibers are evaluated. results show that added have a negligible influence on kinetics. However, internal curing effect saturated competition induced by dry visualized. As fiber increases, decrease due reinforcing effects Dry generate more but less than same introduced competition. NMR proven able track transportation in composites.
