Quarry Dust

In the view of the expeditious growth of infrastructure around the globe, there is an acute shortage of building materials and also a very stern problem of the disposal of the remaining and continuously generating waste. The demand of natural sand in the construction industry also has magnificently increased resulting in the rapid depletion of the river beds which are the natural sources of sand. Acute shortage of good quality of sand has resulted in to considerable increase in its price ultimately affecting the construction cost. Thus there is a severe need to identify a suitable substitute of sand which is eco-friendly and can be used effectively in construction practices mainly in concrete which requires sand as fine aggregates. An attempt is required to investigate use of some alternative materials to save precious natural resources. The current study focuses on determining suitability of using quarry dust, which is a waste product from quarry, as fine aggregates in traditional concrete. During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared. The compressive strength of concrete was determined after replacing sand with quarry dust in various ratios. The results of the study showed encouraging results for replacement of 50% of sand with quarry dust.

Abstract The use of industrial waste has raised great interest regarding its potential of contributing both to the reduction of costs and to sustainable development. In this context, there has been an increasingly high number of studies addressing the use of alternative materials in the construction industry, especially when considering the difficulty in obtaining building materials near urban centers, which results in an increase in the final price due to transportation costs. This research has characterized and evaluated the use of crushed marble waste to replace natural sand in the production of mortar. Many admixtures of mortar were subject to research regarding their physical and mechanical properties. It has been concluded that mortars produced with sand made of crushed marble waste have improved mechanical properties when compared to traditional mortar.

Recent Developments

The performance of asphalt concrete mixtures is influenced by the properties of the included aggregates, such as grading, shape (angularity and elongation), and texture (roughness). Complete and accurate quantification of aggregate properties is essential for understanding their influence on asphalt concrete and for selecting aggregates to produce high-quality paving mixtures. Recent developments in the use of digital image analysis techniques for quantifying aggregate morphological characteristics in asphalt concrete are summarized. Image morphological characteristics were used to quantify flatness and elongation of coarse aggregates, to estimate the proportion of natural sand in fine aggregates, and to correlate aggregate characteristics with engineering properties of asphalt concrete mixtures. Image analysis of sections also revealed information about the grading, shape, and orientation of coarse aggregates in a mixture. An overview is presented of the broad range of useful pavement engineering applications of this relatively new approach for evaluating aggregate characteristics.

Quarry Dust

Concrete plays important role in the construction of structures. The need for concrete increases day by day. Material required for concrete are getting depleted, so there is a requirement to find alternatives. At the same time the alternative materials should posses the property of the actual materials used in concrete and also they must provide the required strength to the concrete. Normally Concrete is firm in compression but anemic in tension and shear. The purpose of this study is to find the behaviour of concrete reinforced with hybrid macro fibers. By adding Glass fibers in percentages like 0.2%, 0.4%, 0.6%& 0.8% to the concrete, the properties like compressive, flexural and split tensile strength are investigated. The optimum percentage of glass fiber was found to be 0.4%. Quarry dust has been widely used in structures since ancient times. The present study is aimed at utilizing waste Quarry dust (WQD) in construction industry itself as fine aggregate in concrete, replacing natural sand and also by adding the optimum percentage of glass fibers. The replacement is done partially and fully in the various proportions like 0%, 25%, 50%, 75% and 100% and its effect on properties of concrete were investigated. The optimum percentage of the concrete by adding 0.4% of glass fiber and the proportions was found to be 25%.

The construction industry is the largest global consumer of materials, among which sand plays a fundamental role; now the second most used natural resource behind water, sand is the primary component in concrete. However, natural sand production is a slow process and sand is now consumed at a faster pace than it’s replenished. One way to reduce consumption of sand is to use alternative materials in the concrete industry. This paper reports the exploratory study on the suitability of aquaculture byproducts as fine aggregates in concrete mixtures. Seashell grit, seashell flour and oyster flour were used as sand replacements in concrete mixtures (10%, 30% and 50% substitution rates). All the mixtures were characterized in fresh and hardened states (workability, air content, compressive strength and water absorption). Based on compressive strength, measured at 7 and 28 days, seashell grit provided the most promising results: the compressive strength was found to be larger than for conventional concrete. Moreover, the compressive strength of the cubes was larger, when larger percentages of seashell grit were used, with the highest value obtained for 50% substitution. However, for oyster flour and seashell flour, only 10% sand substitution provided results comparable with the control mixture. For the three aggregates, workability of concrete decreases with fineness modulus decrease. For mixtures in which shell and oyster flour were used with 30% and 50% substitution percentages, it was necessary to increase the quantity of mixing water to allow a minimal workability. In conclusion, considering the promising results of the seashell grit, it is suggested to study further the characteristic of the material, also considering its environmental and physical properties, including acoustic and thermal performances. Higher substitution percentages should also be investigated. This research adds to the relevant literature in matter of biobased concrete, aiming at finding new biobased sustainable alternatives in the concrete industry.
