اجرایی نمودن دستاوردهای تحقیقاتی بصورت پروژه های عمرانی و صنعتی گامی مهم در راستای پیشرفت هر مملکتی خواهد بود. "بتن خودمتراکم" یکی از انواع بسیار جالب بتن های توانمند است که متاسفانه درکشور ما به دلایل مشکلات اجرایی به ندرت از آن استفاده می گردد. در همین راستا تحقیقاتی در مرحله اول پژوهش صورت گرفت و نسبتهای استفاده فوق روان کننده به آب و پودر سنگ مرمروتراورتن به سیمان در پروژه های اجرایی بدست آ...
In recent decades, the use of self-consolidating concrete has become widespread. Hence, recognizing the various properties of self-consolidating concrete are essential. In this study, several mixture designs have been tested and final mixture design of crushed tile aggregates which were replaced by 0%, 25 %, 50%, and 100% volume percentage of natural aggregates were conducted. To evaluate fresh...
Shrinkage can be critical factor for the design of structural members due to the length changes by the timedependent deformation. Given the high fluidity and different mixture proportions of SCC, the shrinkage of such concrete can differ from those of conventional concrete or HPC of normal consistency. Proper estimate of autogenous shrinkage of self-consolidating concrete (SCC) can provide engi...
Self-compacting concrete is a new high performance concrete with high ductility and segregation resistance. In recent years, construction material manufacturers have focused their attention on lightweight concrete and have strived to use lightweight concrete, if possible, in load-bearing parts of buildings. Concrete with both self-compacting and lightweight properties is favourable in this cont...
The new generation of innovative projects has led to the use of greater amounts of reinforcement and the development of concrete with specific characteristics. It is necessary to use a material that ensures the uniformity of the cross section, as well as the adherence of the existing reinforcement, and due to this, the self-consolidating concrete becomes an technique alternative has great poten...
