1. Introduction Sand is a main constituent of conventional concrete, which needs to satisfy the requirement of rational fineness modulus with particle gradation. Natural river sand is one of the main ingredients of the concrete but is becoming expensive for various reasons. Also, the concern for environment is making A Sustainable Concrete with Manufactured Sand in Different

The sand A is the CEN Standard sand 0/2 according to EN 196-1. The sands B and C are commercial 0/4 natural sands provided by two different quarries from the north-western part of France.Using different pro portion of this robo sand along with sand the required concrete mix can be obtained.

Traditional natural river sand is used as a fine aggregate for concrete, but due to the severe environmental situation in recent years, many places have asked for a ban or restriction on the extraction of river river direction. Cement, sand and aggregate are basic needs for any construction industry. Sand is a prime material used for preparation of mortar and concrete and which plays a major role in mix design. Now a day’s erosion of rivers and considering environmental issues, there is a scarcity of river sand.STUDY THE EFFECT OF PARTIAL REPLACEMENT OF

The focus in the present study for Vietnam was on m-sand sand as alternative for river sand, and different ashes as alternatives for cement in concrete. The investigations comprised concrete lab tests according to the formulations of concrete strength class C 25/30 in accordance with DIN EN 206, followed by a lifecycle In construction Industries, superior fresh and hardened concrete qualities play a significant role in which self-compacting concrete (SCC) is widely introduced. On the other hand, considering the depletion of river sand, manufactured sand (M-sand), created by crushing rock deposits, has been recognized as viable. However, still, there is a lack of Buildings Free Full-Text Impact of M-Sand on Rheological

With a gradient of 5%, manufactured sands with fines contents of 0%, 5%, 10%, 15%, and 20% were blended to produce concrete samples. A river sand control mix was adopted to study the effect of different fines contents on the performance of C60 manufactured sand concrete after carbonization. The mix proportion is shown in Table 4. River sand can be used for making mortar and plastering. Mortar is a mixture of Sand, cement, and water commonly used in construction to hold bricks and stones together. The Sand can be used to form the base of mortar and combined with cement to create a strong and durable mortar. Additionally, river sand is also used for plastering walls.Exploring the Difference in M Sand and River Sand

manufactured sand at optimum level. In this study, the M30 grade of concrete mix was chosen as the basic mix for the analysis. The manufactured sand is used to partially or completely replacement of the natural sand as the fine aggregates. In this study, the results showed that manufactured sand can be the substitute for natural sand the construction sector. For the studied the river sand of zone II is utilized in all the references. 3.3.2 MANUFACTURED SAND (MS) M-Sand confirming to zone II as per IS:383-1970 is utilized.

The comparison was carried out for M30 grade and M40 grade when natural sand was partially replaced by m-sand in the mix of concrete [26]. The use of ash obtained from the fuel of palm oil in terms of replacing natural sand up to 40%, concrete obtained is foam in nature because of the properties associated with material [27].The primary distinction between River Sand and M Sand is where it comes from.
