Abstract Quarry dust is considered as a possible source of natural sand or fine aggregate in concrete construction work. This could reduce the problem of dumping of quarry dust as a byproduct from stone crusher factory. The experimental work investigates the optimum quarry dust percentage which can be adopted as replacement of fine aggregate in concrete mainly for rigid pavement. The quarry dust is added at different percentages of 0%, 20%, 40%, 60%, 80%, and 100% replacement of fine aggregate for M35 grade concrete thereby to find out the optimum content of quarry dust that can give better strength in concrete. Mix design has been developed for M35 grade of concrete as per IRC 044 – 2017(Mix Design for Concrete Pavement) and mix design ratio is found as 1: 1.6: 2.62 by using Sulfonated naphthalene formaldehyde (SNF) as an admixture at 1%, and 2%. The required water cement ratio was obtained as 0.39 according to table no.9 of IRC 044 for the target strength of 42.5 N/mm2. Optimum strength and workability test values of concrete made up for various proportions of quarry dust along with SNF are compared with conventional concrete of natural fine aggregate after 7 days and 28 days curing. It is found that the strength increased with the increase in curing time and the maximum strength at 28 days curing and 60% quarry dust replacement with 2% addition of SNF. The maximum strength of quarry replaced concrete is obtained as 40.3MPa, 5.6MPa, and 5.1MPa for compressive, flexural, and split tensile respectively.

Demand for natural sand in concrete is increasing day by day since the available sand cannot meet the rising demand of construction sector. This paper reports the experimental study undertaken to investigate the influence of partial replacement of cement with Ground Granulated Blast Furnace Slag(GGBFS) in concrete containing quarry dust as fine aggregate. The cement was replaced by 10%, 20%, 30%, 40% and 50% of GGBFS and tests were conducted to determine the optimum level of replacement of GGBFS in quarry dust concrete. The specimens were subjected to compressive strength, split tensile strength, flexural strength, and bond strength tests at 7days, 28days, 56days, 90days and 150 days. The resistance to corrosion is evaluated based on the performance of the concrete for the penetration of chloride ions by means of impressed voltage technique in saline medium and Gravimetric weight loss method. Results herein reveal that an increase in slag proportion increases the strength properties and decreases the rate and amount of corrosion of reinforcement and among the various percentages of replacement 40% is found to be optimum with better strength and corrosion resistance properties.

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%.

About 30% of the ceramic production all over the world considered as waste. This huge amount of ceramic waste can be recycled in the construction industry, especially in concrete mix design, which is the main scope of this research. Ceramic wastes could provide many advantages rather than sustainability. It is considered economical and can replace cement, coarse aggregate, and fine aggregate, such as sand. In this study, several concrete mixtures were designed according to the ACI standards to assess the ceramic waste concrete for fresh and hardened properties in terms of slump, concrete compressive, splitting tensile and flexural strengths. Six mixes included with 0%, 10%, 20%, 30%, 40% and 50% replacement of coarse aggregate by crushed ceramic waste. By comparing the results between ceramic waste concrete and conventional concrete specimens, the optimum mix design was found to be at 30%-coarse aggregate replacement. Scanning electron microscope tests performed on the concrete specimens to examine the bond between the particles, the porosity, and the elementary composition of the specimens. The percentage of savings in cost estimated when using the optimum mix design (30% coarse aggregate replacement) was about a 30% reduction in the construction cost per the Egyptian market.

Abstract In construction industry nowadays, self-compacting concrete (SCC) is a concrete technology innovation which gives more benefits over conventional concrete. SCC was invented to improve concrete durability without using any vibrator while placing it into formwork. In order to conserve natural sand, quarry dust (QD) as a waste and sustainable material has been incorporated to replace fine aggregate in SCC. In this study, conventional concrete and quarry dust in self-compacting concrete (QDSCC) mixes consist of 0%, 10%, 20%, 30%, 40% and 50% QD were prepared. The workability test was conducted to determine the performance of fresh concrete and ensuring all the QDSCC properties follow the acceptance criteria for SCC. Meanwhile, the hardened concrete specimens were water cured for 7, 28 and 60 days to conduct water absorption test. This research aim is to determine water absorption of incorporating sustainable QDSCC. Thus, it resulted that 50% of QDSCC has achieved the lowest water absorption of QDSCC as compared to other dosages. Finally, sustainability in concrete technology can be promoted by incorporating QDSCC.

Nowadays there is an increase in environmental knowledge and its effects on the environment, the disposal of waste products from industries are being big deal to manage. Such waste materials cannot be dumped on any lands, due to this reason it is difficult to manage waste materials. After so many investigations finally conclude that waste material can be utilized in the construction as additives, such materials can reduce the cost of construction and gives more strength compared to conventional concrete. These products can be utilized to partial replacement of cement. In this investigation, we are using Silica fume/ Micro silica as a partial replacement of cement. From this combination, we can improve the strength, workability and resist cracks in concrete. To reduce water content PAR PLAST SPL super plasticizer is used. The present investigation is to determine the strength behavior of Silica fume/Micro silica and fibres in Rigid pavement. The concrete mix design is as per IRC 44 2009, and it is proportioned to set target mean strength as 40 Mpa. The water-cement ratio as per mix design is 0.38. Specimens was casted and cured for various percentages that are 0%, 2.5%, 5%, 7.5% and 10%. With this constant percentage of fibres was added that is 1% Polypropylene fibre and 0.5% Glass fibre. This specimen tested for 3, 7, 28 days for cubes and 7, 28 days for beams and cylinders. From this investigation, Cement can be replaced with Micro silica to improve strength properties like bending and tensile strength. The Silica fume/ micro silica found at 7.5% optimum dosage, up to this percentage cement can be replaced.
