The most significant development in the construction and implementation of concrete in the last three decades is the use of self-compacting concrete (SCC). The use of self-compacting concrete, is a process useful in the construction industry to solve concrete casting problems. Self compacting concrete, also referred to as self consolidating concrete, is able to flow and consolidate under its own weight and fill the workform without need for vibration. It is cohesive enough to fill the spaces of almost any size and shape without segregation or bleeding. This makes SCC particularly useful wherever placing is difficult, such as in heavily reinforced concrete members or in complicated workforms. The main difference between self consolidating concrete and regular concrete is the fresh properties of them. Workability of SCC is described in terms of filling ability, passing ability, and stability, and is characterized by specific testing methods. Obtaining these features makes SCC a mix with less coarse aggregates and more binder than regular concrete. Despite of all the above mentioned advantages, this concrete like ordinary concrete has also some disadvantages. High shrinkage is considered as weakens of this concrete. Among properties of self compacting concrete, shrinkage is a property which rarely has been studied and investigated; therefore, in this field very less information has been reported or published. In general, shrinkage is considered as the commonest cause of cracking. In structural components which their deformation has been limited if related controls are not performed, contraction causes tension and as a result crack so that this can lead to incompetency of service, durability and shear strength. In this thesis, it is aimed to proceed to investigate experimentally and present an analytical model of drying shrinkage of self compacting concrete and the factors effective on it. The first part, twenty foure SCC mixtures with water to binder (W/b) of 0.35, 0.40 and 0.45 were prepared using single and binary binders that was conducted for determine the effect of microsilica and nanosilica on compressive strength (7, 28 and 90 days) and drying shrinkage of SCC. The second part three mixtures was used, which had water to binder 0.45 and 10% microsilica with coarse aggregate volume (29%, 34% and 39%). Also, it was designed for studying effect coarse aggregate volume on compressive strength and drying shrinkage of SCC. In the last part, 24 simples were used to investigate the permeability of self compacting concrete. In this study, self-compacting concrete in the fresh phase (past) was subjected to slump flow test, T50 and V-Funnel. To measure of drying shrinkage of concrete, 285×75×75 mm prism specimens were used based on ASTM C157 standard for 26 mixed design. Obtained results indicated that generally by increase of percentage of Nanosilica (N) up to 2 percent, compressive strength increase and drying shrinkage decrease. Also test results showed that The Synergic Effect of Nano-silica(N) and Micro-silica(M) is best and between all affecting parameters, replacing combnation Micro-silica and Nano-silica has best and most influence 126 on the compressive, drying shrinkage and permeability of SCC. To investigate effect of water to binder ratio, amount of this parameter was selected 0.35, 0.40 and 0.45. The more increase of water to binder ratio of concrete, the more decrease of compressive strength and also the more increase of drying shrinkage. Increase of drying shrinkage rate in lower water to binding materials ratio is more obvious. By increase of coarse aggregate volume from 29% to 34%, amount of compressive strength increase in all ages but by increase of coarse aggregate volume from 34% to 39%, compressive strength decreases but in general by increase of coarse aggregate volume, drying shrinkage continuously decreases. At last, according to the proposed models for ordinary concrete and experimental results, a model is presented to predict drying shrinkage in concretes of this research.
