Compressive Strength of Concrete -Cube Test, Procedure ...

Compressive Strength = Load / Cross-sectional Area. Procedure: Compressive Strength Test of Concrete Cubes. For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical molds of size 15cm x 15cm x 15cm are commonly used.

Prodution of Concrete Aggregates with High Strength by ...

Several series of concrete aggregates with different content of steel slag, blast furnace slag, coal gangue and fly ash were prepared. The reasonable ratio of raw materials and process parameters to prepare the aggregates were determined by measuring the water absorption, crush indicators and apparent density of the aggregates. The mineral composition and morphology of the aggregates were ...

Effects of Ground Granulated Blast Furnace Slag in ...

Strength gain is not only an inherently important property, but it also indicates the quality of the overall cement matrix. Using slag cement as a replacement material for OPC changes the rate of strength gain because the hydration properties of slag cement are different from OPC. Slag cement is a latent hydraulic material, meaning that with use of

Recycled Glass in Concrete – Concrete Ideas

 · The compressive strength varies with the compressive strength of the original concrete and the water-cement ratio of the new concrete. It has been found that concrete made with recycled concrete aggregate has at least two-thirds the compressive strength and modulus of elasticity of natural aggregate concrete.

Spheroidal Beads from Boiler Slag and Fly Ash

The crush strength was calculated by dividing the measured force by the particle cross-sectional area Α = πd2/4, where d = particle diameter. The fly ash beads tended to crush ... strength, and hardness of the slag beads is comparable to those of the glass beads. However, the chemical purity of the slag beads is not as good as that of soda ...

Strength Properties of Steel Slag in Concrete

Figure 4: Compressive Strength Graph for M 30 grade of Concrete • From both of the above graph i.e. M25 and M30, the compressive strength of concrete is increased gradually from 0% to 20% and achieved a maximum value at a replacement of 30% Steel slag in fine aggregate afterwards decreased for 40% replacement of steel slag.

The Complete Guide to Crushed Stone and Gravel

 · Unlike crushed stone, gravel is usually sold and used in its natural state. If it is crushed, gravel loses its unique smooth rounded texture and becomes crushed stone. It is important to note that some contractors refer to any stone in certain size ranges as "gravel," even if it is crushed stone.

Crushed stone

The slag cools to become a stone-like material that is commonly crushed and recycled as construction aggregate. In addition, 4.53 million tonnes of crushed stone was used for fillers and extenders (including asphalt fillers or extenders), 2.71 million tonnes for sulfur oxide removal-mine dusting-acid water treatment, and 1.45 million tonnes ...

Slag cement strength

Slag cement increases the compressive and flexural strength of conventional concrete (Figures 1 and 2) and is often a vital component in producing high strength concrete. 28-day strengths generally increase as the percentage of slag cement increases, up to about50 percent slag cement as a percent of cementitious material.
