Flexural Toughness Properties of Reinforced Steel Fibre
The influence of steel fibre addition on the flexural properties of geopolymer based cementitious matrix was investigated in the present study. Slag based geopolymer mixtures were prepared with different binder and aggregate combinations. Strength gain and hardened properties of different geopolymer concrete mixtures were evaluated using accelerated curing techniques subjected to hot air oven ...
Response Characteristics of a Steel Fiber-Reinforced
The utilization of ultra-high-strength concrete offers a weight reduction of concrete structures and improvements in disaster protection performance. Recently, porosity-free concrete (PFC) having the world's highest compressive strength of 400 MPa has been developed, and its basic mechanical properties were determined; however, its impact-resistant capacity is yet to be examined.
Types of Concrete & Characteristics | Concrete Classification
The concrete in which common ingredients i.e. aggregate, water, cement are used is known as normal concrete. It is also called normal weight concrete or normal strength concrete. It has a setting time of 30 - 90 minutes depending upon moisture in atmosphere, fineness of cement etc.
Build Custom Molds to Pour a Concrete Japanese Lantern
Jan 19, 2016 · Now that you’re a concrete expert, it’s time to tackle the trickiest piece, the window box. This piece has some thinner sections, where regular quick-set concrete would likely crack. So you’ll use a specific concrete called “construction grout” or “structural grout.” Mix a normal-sized batch, about ⅓ of the 50lb bag.

Punching Shear Strength of GFRP-RC Interior Slab-Column
Test results revealed that increasing the GFRP reinforcement ratio or the concrete strength increased the connection capacity and decreased the deformation of the tested slabs. Moreover, the GFRP-RC connection that has similar reinforcement rigidity to the steel-RC one showed comparable capacity and deflection at failure.
