Abstract: Concrete is weak in tension and strong in compression. The inclusions of fibers in concrete significantly improves its compressive as well as tensile strength. The use of different types of fibers have shown positive responses among the researchers. It has long been known that curing concrete during cold weather can result in an inferior product with substandard properties. Curing also takes much longer, adding to job costs and extending the time before the concrete surface can be used. There are many accelerators available in the market, but Calcium Chloride continues to be one of the most preferred one. In this study, Alkali resistant glass fibers (0%, 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5% and 4%) were used in the concrete M30 mix. The optimum glass fiber percentage that can be added to the concrete is found by comparing both tensile and compressive strength of the GFRC. Trial mixes of normal M30 concrete by adding different percentages of Calcium Chloride (0%, 0.5%, 1%, 1.5%, 2%, and 2.5%) as curing agent is also prepared. The optimum percentage of calcium chloride that can be added to the concrete is found by comparing the compressive strength of the con- crete. The compressive strength of the GFRC using calcium chloride integral cur- ing is found after 7, 14 and 28 days. The test results are then compared with GFRC using normal curing.
