The concrete crusher is suitable for medium or fine crushing of a variety of ores and rocks which have less than 250Mpa crushing compressive strength in metallurgical industry, mining industry, building industry, chemical industry, water conservancy and railway sectors.
Cement type and curing conditions are two factors that affect the amount of strength gain to be expected. Concrete, by Mindness and Young, gives a general rule: The ratio of 28-day to seven-day strength lies between 1.3 and 1.7 and generally is less than 1.5, or the seven-day strength is normally between 60% to 75% of the 28-day strength and usually above 65%. The cylinder that broke at 1980 ...

Magazine of Concrete Research - ICE Virtual Library. Summary As part of an investigation on the effect of temperature on the crushing strength of concrete, tests have been carried out using 2 in. diameter by 4 in. long specimens made with ordinary Portland cement, river sand and gravel aggregate, having various mix proportions and water/cement ...
Low W/C ratios and the use of silica fume make concrete mixes significantly less workable, which is particularly likely to be a problem in high-strength concrete applications where …
In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant. The internal forces in common shapes of structure, such as

Abstract: This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test.
Most concrete mix designs use the same type of raw materials: cement, water and aggregate (usually sand and stone), in different ratios. Some types of concrete have additional materials added to give specialist qualities, such as:

prescribes a standard concrete mix ratio that he thinks will produce the required concrete. He may also indicate the type and size of aggregate to be used. The Builder/site engineer prepares the mixes based on the ratio that has been prescribed. 2.1.3 Designed Mixes In these mixes the performance of the concrete is specified by the designer but the mix proportions are determined by the ...
Low w/c ratios and the use of silica fume make concrete mixes significantly less workable, which is particularly likely to be a problem in high-strength concrete applications where dense rebar cages are likely to be used. To compensate for the reduced workability in the high strength concrete mix, superplasticizers are commonly added to high-strength mixtures.
The strength of these type of concrete will vary from 10 MPa to 40MPa. The normal strength concrete has an initial setting time of 30 to 90 minutes that is dependent on the cement properties and the weather conditions of the construction site.

Abstract. Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate's shape, size, texture, grading and crushing type.
Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during production of concrete etc. Test for compressive strength is carried out either on cube or cylinder.
