In order to comply with current trends concerning sustainability, saving of primary materials and energy savings, this paper addresses Eco-concrete. The major focus thereby is on the increased efficiency of cement use. Applying a new mix design method for concrete, cement contents can be decreased and partially be substituted by other fine powders, preferentially by waste powders which have no ...

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. Marble Sludge Powder (MSP) can be used as filler and helps to reduce the total voids content in co...

Concrete is a vital ingredient in infrastructure development with its versatile and extensive applications. The Indian construction industry today is consuming about 400 million tons of concrete every year and is expected to reach a billion tons in less than a decade. It is the most widely used construction material because of its mouldability into any required structural form and shape due to ...

Based on the bending experiment for two-span continuous post-tension beams with unbounded tendons and externally applied CFRP sheets, the analysis of the stress increment of unbonded tendons is monitored in the loading process. Since self-compacting concrete (SCC) is a suitable innovation,, understanding the implementation of this type of concrete on the ultimate unbonded tendon stress is criti...

Self-compacting Concrete is one of the new innovative types concrete, and it used widely in construction several industries. This type concrete can be made by using different admixtures their combinations. The main aim SCC to improve durability structure also improves workability structure. Nowadays large structures, isn't easy compact reinforced without voids. overcome self-compacting concrete...

Self compacting concrete (SCC) is an innovative development of conventional concrete, which requires high binder content to increase its segregation resistance. This paper presents a comparative study on the use of different materials as binder content in SCC and their effects on the workability and strength properties are checked. Different combinations of Fly ash, Metakaolin and Saw dust ash ...

A Lagrangian particle-based method, the smooth particle hydrodynamics, is used to model the flow of ultra-highperformance, self-compacting concretes containing short steel fibres which behave like a non-Newtonian fluid described by a Bingham-type constitutive model. An incompressible smooth particle hydrodynamics method is used to simulate the flow after the kink in the shear stress against the...
