2021.7.30 Unavailability and shortage of natural sand can also be balanced by using crushed stone. Manufactured sand is also known as crushed sand and stone dust and it is made by crushing and grading suitable granite stones and rocks. As we all know that river beds are used to obtain natural sand. Now the depletion of natural sand has become a

2023.6.3 The local practice uses natural crushed sand (NCS) instead of river sand to manufacture the concrete. For this reason, mix with (100% NCS) designated 100NCSC* marked as the control mix. Four types of modified sand concrete have been developed 100NCSC*, 100RCSC, 50NCSC, and 50RCSC, respectively.

2023.10.16 Purpose of Crushed Sand: Crushed Sand is used instead of natural sand since the desire for sand has surged due to the fast-increasing construction projects, resulting in a lack of appropriate river sand throughout most regions of the world. Crushed sand of the scarcity of high-quality river sand for building, the usage of artificial sand has

2017.12.25 Natural sand / River sand has been used in construction for many centuries. Recently for past few years due to various reasons, we have to use manufactured sand / crushed sand. Let’s discuss about the properties and applications of manufactured sand comparing with Natural sand. 1. Sourcing: Natural sand is sourced from river beds.

2020.7.1 One of the solutions is to use crushed sand to replace natural sand as aggregate in concrete, especially the study of using crushed sand to make high-strength self-compacting concrete. Crushed sand is an aggregate of angular shape and surface roughness that hinders the self-compacting of the concrete mixtures. Combination with

2019.11.23 100% in the amount of superplasticizer was required to keep the same slump when only 10% of natural sand was substituted by crushed waste glass aggregate. Increasing the replacement level of natural sand by the crushed glass aggregate required further increase of the superplasticizer content to keep the same slump value of 55 ± 5 mm.
Read More2020.11.19 Natural sand and crushed sand are the main construction sands for infrastructure in China. The shortage of natural sand has led to increasing demand for crushed sand . Crushed sand with particle size less than 4.75 mm is the primary material of asphalt concrete. The larger the particle size, the more obvious the shape of the particle.
