This paper presents a study on the combined use of two by-products, namely quarry dust (QD) and ferronickel slag (FNS), as a full substitute for natural sand to improve the greenness of concrete production. Quarry dust was used in increments of 25% to a maximum of 75% substitution, where nickel slag was used as the remaining …
The result shows that 25% of quarry dust and 75% of cement is the best percentage that can be used in concrete mixture to reach the standard strength. From an economic point of view, the proposed optimum concrete mix was found to be the most economical with the reducing of RM 33 per 1 m 3 of the concrete mixture. The results …

Abstract. An integral part of concrete mix proportioning is the preparation of trial mixes and making adjustments to such trials striking a balance between the requirements of placement, strength, and durability. When coarse aggregate characteristic strength is lower than the levels of strength of the concrete desired, different methods, …
Even though cement replacement by waste quarry dust leads to increased water absorption in ordinary concrete, it is still possible to develop good quality concrete mixtures of low permeability, by including waste quarry dust at a content of up to 15% cement replacement and maintaining low water-to-binder ratios (Kartini et al., 2014).
From an economic point of view, the proposed optimum concrete mix was found to be the most economical with the reducing of RM 33 per 1 m 3 of the concrete …

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
It has been observed that quarry dust requires more water to attain same slump when compared to control concrete. For mixes M20 and M25, quarry dust concrete with …
Title: Utilization of Basaltic Quarry Dust as a Partial Replacement of Cement for Hollow Concrete Block Production Author(s): Bahiru Bewket Mitikie, Yohannis Lemma Alemu & Shumet Getahun Reda Publication: IJCSM Volume: 17 Issue: Appears on pages(s): Keywords: basaltic crusher dust, blended cement paste, hollow concrete block, wall …
From the calculation of the proportion of conc rete mixture, it can be seen the use of cement in . ... This work is related to study the compressive strength of concrete using quarry dust as fine ...
Concrete is the most essential material used in the construction work. It is having high compressive strength, low tensile strength and brittle in nature with a proportioned mixture of cement, fine aggregate, course aggregate, water, etc. Development in the infrastructure is a key factor in governing the demand for concrete.
This paper presents the feasibility of the usage of Quarry Rock Dust as hundred percent substitutes for Natural Sand in concrete. Mix design has been …
One of the best mixture ratios for a concrete slab is 1 : 3 : 3 (cement : sand : stone), this will produce approximately a 3000 psi concrete mix. This mixing ratio is excellent for a shed slab, but it's also good for most concrete patios, footings, steps, and foundation walls.
Therefore, water to cement ratio was increased for concrete with quarry dust to sustain similar workability of conventional concrete [31,32]. On the other hand, the presence of quarry dust improved the mechanical characteristics and durability aspects of the concrete [29,33]. Quarry dust was also used in self-compacting concrete.
A commercially available Portland cement classified as Type III by ASTM C150 [19] and Type CPV ARI by the Brazilian Standard ABNT NBR 5733 [20], was used in all of the mixtures.According to the cement manufacturer, it had a Blaine fineness of 394 m 2 /kg, and specific gravity of 3.12. The oxide composition of the cement is shown in …
In this paper a generalized method is advanced to proportion concrete using quarry wastes, namely, cuddapah and marble in concrete, as coarse aggregate. Concrete is regarded as a composite of cement mortar matrix and coarse aggregate.

Concrete Mix Ratio. To make concrete, you'll need four basic ingredients: cement, sand, aggregate, water, and additional mix. Concrete mix design is the method of determining the correct proportions of cement, fine aggregate (sand), and aggregates for concrete to achieve the target strength of the prepared concrete mix.. The advantage of the …

A pre-packaged bag like this is basically a 1 : 2 : 4 mixture for concrete, this is the standard for a lot of concrete mixtures. These concrete mixture ratios are designed for the concrete to reach full strength at or around 28 days old. Curing the concrete can be done by keeping it wet after the first day until the concrete is 7 days old.
