By attention to Iran’s seismicity condition, light weight and resistant structures, using of new capable concretes seems to be necessary; such as self-consolidating lightweight aggregate concrete that either use from lightweight concrete benefits in reducing the dead load of the building, sound insulation, heating insulation and other improved properties and or have workability and power of self-consolidating concrete to flow into the framework, passing through the compacted reinforcement and is capable of self-compacting properties. Concrete under destructive chemical and physical attacks quickly and in a shorter time than what for it is considered as useful life, damaged and lose its strength. This issue in structures such as dams, power plants, bridges and tunnels that life of its operation is very long and repair and retention costs is higher that initial construction costs in many cases, has a particular importance. For example physical destructive factors can be cited to process freeze and thawing. If sufficient durability of concrete against freeze and thaw cycles does not have the exposure to attacks in very less time of the useful life will be destroyed. The aim of this study was to evaluate and compare the effects of pozzolans and also effect of water absorption of lightweight aggregate on the durability self-consolidating lightweight concrete against the destructive cycles of freeze and thawing. Frosts effect on the concrete can be investigated by measurement compressive strength, elongation, weight change and change of water absorption concrete samples. Considering the effect of the water-cement ratio on the durability of concrete in the frost condition, the water to cement ratio in this study is considered equal to 0.42. Pozzolans used in this study are, silica fume and metakaolin. In preparing the mix designs a mix design without pozzolans and two mix designs containing silica fume or metakaolin replacement cement to 10% by weight is used. Lightweight aggregates are used in three modes. The first with a 24-hour saturation that water absorption percent is 6.65% (short-term saturation), the latter with two months saturated that have a water absorption percent 15.31% (long-term saturation) and the third case is dry lightweight in the open air. Therefore by considering the combined modes for a total of 9 mix designs is used. From the each of the mix design, 21 of the 10 cm cube made. In accordance with standard ASTM-C666-B samples tested were frozen and thawed. To compare the performance of mix design against frost, changes in weight, length, water absorption and compressive strength before and after exposure to freezing conditions, were studied. In this study it was shown that saturation of the lightweight aggregates before mixing is a good strategy for improvement the fresh properties of self consolidating concrete and prevents a severe slump loss that occurs in concrete made with dry lightweight. But after spending freeze and thaw cycles decrease the compressive strength more than mix designs that containing dried lightweight aggregates. Pozzolanic materials could in addition to increase the strength of all ages have a significant impact on the durability of concrete against freeze and thaw agent. By comparing the two used pozzolans in research silica fume have the most effects on increasing the strength, reduced weight changes, length and concrete water absorption.
