Self Compacting Concrete(SCC) is a new type of concrete to which considerable importance has been attached by researchers, manufactures and users, because of specific characteristics that have shown in fresh state and it is now being frequently used in the world. With respect to characteristics expected by self compacting concrete and in order to achieve self compactibility, it is essential to use more powder materials in it, in comparison with conventional concrete . To do so, pozzolans are generally used to make SCC. Service life of concrete, is a time that in which concrete is sufficiently strong to the design load and concrete durability is one of the factors that has considerable influence on the service life of concrete. a durable concrete has more resistant to chemical and physical attacks. Freezing and thawing is one of the physical destructive factor and if a concrete has not enough resistance regarding freeze-thaw cycles, it will deteriorate in a time period much shorter than its service life by being exposed to their attacks.This research aims to investigate and compare the pozzolans effects on Frost resistance of conventional and fiber reinforced self compacting concrete. The effect of freezing and thawing on concrete can be analyzed through measuring compressive strength and length, weight and water absorption changes in concrete samples. Water cement ratio is one of the most important parameter that has a considerable effect on frost resistance of concrete, Hence, water cement ratio was considered constant in this study. The pozzolans used in this study were silicafume, metakaolin and zeolit and the polypropylene fibers were used to reinforce the concrete. The mixtures were divided into two groups. These two groups of mixtures contained 0 and 0.1% poly propylene fibers (PP) by volume, respectively. The single binder was made by 100% type I Portland cement. The binary binders contained silica fume (5%,10%), Metakaolin (5%,10%) and Zeolite (5%,10%) that were replaced with the same weight of cement. In addition, in order to a better study of the effect of fibers on concrete durability on frost resistance, the volumetric fiber ratios of 0.05% and 0.15% were only used in the mixtures containing 10% silicafume. To investigation the combined effect of pozzolans, 3 mixtures with combining 3 above mentioned pozzolans were made ( 5% of each pozzolans was used in any combination). Therefore 19 mixtures were obtained that with respect to the number of required specimen to conduct the experiments(18), totally 342 cubic specimens with dimensions of 10 cm were made. The specimens were tested under freezing and thawing conditions according to ASTM C666 B standard. To compare the mixtures against freeze-thaw cycles, the change in length, weight and water absorption ratio and compressive strength of specimens were analyzed. The results show that replacing percentage of cement with a pozzolan can have a positive and remarkable influence on frost resistant of SCC. Among the pozzolans used in this study, the silicafume had the greatest impact of compressive strength. Although Zeolit had no effect on increase of compressive strength, a desirable performance against freeze-thaw perceived in this regard. Use of fibers(PP) for the purpose of concrete durability against freeze and thaw, have been positive assessed.
