Machine-made sand: self-produced high-quality machine-made sand was produced by the parent rock of Pingkan tun - nel excavation. The compressive strength of the parent rock was 102 MPa, the apparent density was 2723 kg/m 3, and the moisture content was 0.6%. The crushing index of machine-made sand was 18%, the methylene blue value was 0.5 g/
The mechanical and working properties of the machine-made sand concrete reach the optimum condition when the mineral admixture is 20%, the sand rate is 46%, the stone powder content is 10% and the water–cement ratio is 0.30. Comparing different fine aggregate concretes of similar quality, we conclude that the mechanical …
The paste is made of cement and water, while the aggregate is a combo of sand and rock. But dig a little deeper and you'll uncover the amazing complexities of this extraordinary material. Before we dive into the details, let's recap the basic ingredients of …
The densest and strongest concrete is that in which cement paste fills the voids with the sand and the resulting mortar fills the voids in the coarse aggregate. Every grain of sand should be entirely coated with cement. Before the invention of the mixing machine, the entire mixing process used to be done by hand, shovel, shallow box.

The concrete blender is capable of simultaneously blending two aggregates, cement and water, to produce concrete in most any formulation required. The blender features two separate aggregate hoppers, …
It can be seen from the calculation that the carbon emission factor of machine-made sand reaches 7.651 kgCO 2 /kg. The research results of many researchers on the carbon emission factor of natural sand are about 6.6 kgCO 2 /kg. Therefore, the mining process of machine-made sand needs to be improved.
Do you want to know how does the concrete batching plant work?. A concrete batching plant is a type of concrete mixing plant that mixes materials to produce concrete. It is usually made up of a mixer and conveyor belt. The conveyor belt carries the material to be mixed, and the mixer then mixes it with water, cement, aggregate, or …
