Strength Properties of Concrete Using Marble Dust Powder

Abstract

Construction expenses have mostly grown unaffordable in recent years. Civil engineering institutes and stakeholders throughout the world have worked to develop recyclable and resource-saving concrete for building applications in order to reduce these expenses. The majority of environmental issues arise from the disposal of trash in areas where marble sculpting takes place. The marble stone slurry generates both stone slurry and solid wastes, and with the massive discharge of marble trash locally, emphasis has been focused on the utilisation of waste material. This study looked into the use of marble dust powder in concrete, with varied percentages of marble dust (0%, 5%, 10%, 15% & 20%) replaced by sharp sand in M20 grade concrete mixes, while the water cement ratio was kept constant at 0.45. The compressive and split tensile strength of the concrete were evaluated after 7 and 28 days of curing time to determine its quality, performance, and dependability. The laboratory findings revealed that replacing marble dust powder with cement boosted concrete strength by up to 10% in terms of compressive load resistance and tensile strength.

Analysis of compressive strength of sustainable fibre reinforced foamed concrete using machine learning techniques

“…Cement production contributes to the emission of greenhouse gases both directly through the thermal decomposition of calcium carbonate, which releases CO 2 , lime, and indirectly through the use of energy, particularly the combustion of fossil fuels. To maximize the utilization of natural resources in developing countries, it is necessary to investigate the recycling and reuse of refuse materials [6,7]. Modernly, foamed concrete is regarded as an attractive building material due to its flexible production technology, exceptional target properties, and economic advantages [8,9].…”

Study on the Performance Behaviour of Fibre Reinfored Foam Concrete

“…It is utilised as a replacement in the manufacturing of concrete. According to the research that has been published [19][20][21][22][23][24], the lightweight concrete of foamed concrete's early strength is increased by the addition of silica fume, simultaneously it reduces its workability of the concrete. The purpose of this investigation is to find out the effect of fibre reinforced foamed concrete which is prepared by cement replacement by silica fume with the proportion upto 50% with various mix.…”

An Experimental Study on Fibre Reinforced Foam Concrete Using Hybrid Fiber

“…For light weight concrete the purpose of adding fibre is to reduce the crack of the foam concrete at early ages. And also it possess high modulus of elasticity and good tensile resistance [17,18]. The fibre reinforcement can change the brittleness property in the foamed concrete.…”
