What kind of concrete stone crushing equipment is good
Concrete, referred to as concrete, is widely used in civil engineering and shipbuilding, machinery industry and other fields, coupled with the large-scale construction of infrastructure and urbanization in recent years to promote the process, thus making its use more and more, however, what kind of stone for concrete? Which is the best stone crushing equipment?
What kind of stone is used for concrete?
Concrete is mainly made of cement, coarse aggregate (stone), fine aggregate (sand), additives and water mix, after hardening and become a kind of man-made stone, the main indicator of its quality is the compressive strength, and coarse aggregate on the strength of the concrete also has a certain impact, in the beginning of the project, by the person in charge of the technical site to determine the coarse aggregate, commonly used crushed stone (basalt, cobblestone ...) and pebbles. The coarse aggregate is usually crushed stone (basalt, pebbles...) and pebbles.
Difference between concrete crushed stone and pebbles
Crushed stone is natural rock, pebbles or mine waste stone made by mechanical crushing, screening, particle size greater than 5mm rock particles.
Pebbles are made of natural weathering, water transport and sorting, accumulation and become, particle size greater than 5mm rock particles.
When the stone strength is equal, crushed stone surface than pebble surface rough, it and cement mortar bonding than pebbles, when the water-cement ratio is equal or the same ratio, the two materials formulated concrete, crushed stone concrete strength than pebbles high.
Selection of crushed stone, concrete strength to a certain extent, mainly depends on the hardness of the stone, so it is very important to choose the type of stone, high hardness stone such as basalt, if there is no such stone, you can choose the other, through the rock indentation hardness tester or crushing index value test to choose, the stone should also be washed, washed mud and stone powder, the grading of the stone should be continuous.
Generally mined large stones with a large particle size (about 50 centimeters - 1 meter 2 or so), need to go through the coarse crushing, medium crushing, fine crushing and other processes into the stone required for concrete, there are about 200 kinds of stones on the market, so which one of the crushing stone equipment is good? But also combined with the raw material qualities, size, output requirements, and consider the site conditions, investment budget and other aspects, to reasonably choose and buy, commonly used jaw crusher, impact crusher, cone crusher, etc., the equipment model is complete.
