PDF Influence of continuous plastic fibers reinforcement

Concrete is the most widely used construction material in the world due to its high compressive strength, long service life, and low cost. However, concrete has inherent disadvantages of low tensile strength and crack resistance. Numerous studies on fiber-reinforced concrete (FRC) have been performed in order to

Concrete Construction Archives | PRO CREW SCHEDULE

Concrete contractors are among the most important stakeholders in most construction works. While some sustainable structures are made from pure wood and glass, most commercial and industrial buildings are still made from cement. Today, we will look into the basics, importance and advantages of different cement types used in the construction

Civil Engineering - Research Supported by FAPESP

Numerical analyses of steel reinforced concrete applying the mesh fragmentation and coupling techniques are proposed. The mesh fragmentation technique consists in the introduction of finite interface elements with high aspect ratio between the bulk elements of the mesh, enabling the simulation of crack formation process.

Flexural Behavior of Corroded Reinforced Recycled

Recycling concrete not only reduces the use of aggregate but also decreases the pressure on landfills. As a result, recycled coarse aggregate (RCA) is extensively recommended for new construction projects. However, the flexural behavior of corroded reinforced recycled aggregate concrete (RAC) beams is uncertain. The experimental research presented in this paper was performed to

reinforced concrete beams with recycled aggregates. Three beams with different replaced one condition of aggregates were subjected to the sustained flexural load (0.5Mn) for one year. The results shows that the performance of reinforced concrete beams with recycled aggregates are satisfied with the serviceability criteria in term of deflection.

Use of RECYCLED AGGREGATES In CONCRETE- A Paradigm Shift

The fine aggregate used in the concrete, i.e. recycled and conventional is 100 percent natural. The recycled aggregate are collected from four sources all demolished structures. For both types of concrete i.e. M-20 and M-25, w/c ratio, maximum size of aggregate and mix proportion are kept constant.

Experimental Investigation on the Properties of Recycled

Due to the inherent property of concrete being very weak in tension, efforts have been made to overcome this deficiency by adding various type of fibers like carbon fiber reinforced polymer (CFRP), glass fiber reinforced polymer (GFRP), polypropylene fiber (PPF) and stainlesssteel fiber (SSF) smeared into the concrete mix. The present study involves experimental investigation on the use of
