What is the role of stone in concrete


Sand and gravel are one of the main components of concrete. Sand and gravel play the role of filling and reinforcement in concrete, and play a vital role in the performance and strength of concrete.

Sand and gravel act as a filler in concrete. Concrete is made by mixing cement, sand, stones and water in certain proportions. Sand and gravel have a filling effect between particles, filling the gaps in the cement gel, making the concrete more dense and compact. This filling action helps reduce shrinkage and cracking of the concrete and increases its durability.

Sand and gravel enhance the strength and stability of concrete. The particles of sand and gravel form a mechanical connection with the cement gel, which increases the cohesion and compressive strength of the concrete. Sand and gravel can also improve the shear strength and impact resistance of concrete, and increase the stability of concrete. In addition, sand and gravel can also disperse the stress between cement particles and improve the crack resistance of concrete.

River Water Cyclone Desander

 A cyclone desander is a sand removal device that combines cyclone flow and filtration. It is primarily used to remove solid particles and sediment from groundwater, including groundwater and other water sources. It is suitable for water-source heat pump systems, central air conditioning circulating cooling water, chilled water systems, winter heating and cooling circulating water systems, and industrial cooling circulating water systems. It is widely used in many industries, including the chemical, environmental protection, and food industries, achieving remarkable results in water treatment, including sand removal, turbidity reduction, solid-liquid separation, and sediment separation. Cyclone Desander Concept: A cyclone desander, also known as a cyclone desander or desander, is a device that uses the principle of screening solid particles in the medium as they rotate within the desander. Combining cyclone flow and filtration, it achieves remarkable results in water treatment, in...

Water-Saving Sand Washing Plant

Choosing water-saving equipment and integrating recycling functions is the key to fundamentally reducing water consumption. Select advanced sand washing equipment Bucket-type sand washing machine: The structure is simple, with almost no wearables except for the screen, and the failure rate is low. It adopts a circulating water cleaning method and is one of the relatively more water-efficient mainstream choices currently. Integrated sand washing equipment: This type of equipment integrates sand washing, fine sand recycling, dehydration, and even wastewater treatment functions into one, significantly simplifying the process flow. For example, some new equipment uses built-in bubble flushing technology to improve the flushing effect and avoid secondary cleaning waste caused by incomplete cleaning. Mandatory water recycling system Modern sand washing equipment usually comes with a water recycling system, which can collect, filter, and reuse water during the cleaning cycle. This approach ca...

The difference between quartz and mica

Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.
