Four different concrete mixes with the same cement content and different w/c ratios were designed using normal dolomite aggregate, air-cooled slag by-product and two different types of iron ore aggregates. High performance concrete (grade-M60) can be achieved using superplasticizer to reduce the water/cement ratio; the effect of SF on the This paper investigates the use of dolomite sand waste and BOF steel slag for replacing conventional fine and coarse aggregates for design of high performance asphalt concrete.

This paper aims to assess the influence of clogging on paving material (pervious concrete) drainage characteristics as well as the influence of the properties of an unbound base layer on drainage characteristics of the whole paving system. The clogging influence has been studied measuring the drainage characteristics on pervious concrete Worldwide, approximately 4–5 billion tons of cement and 15 billion tons of crushed aggregates have been produced annually to manufacture 20 billion tons of concrete [15– 17]. by using dolomite quarry waste as a sand replacement at 0%, 25%, 50%, 75%, and 100% by the weight of sand con-Potential of dolomite industrial waste as construction

DRS is a by- product of ACC cements, Coimbatore and they produce around 500 tonnes of DRS per day, which is then dumped into mines. In order to achieve a closed loop system, we further extend the life time of Dolomite Rock Sand in conventional concrete, thereby saving the cost that is generated from using conventional river sand or It is crushed and sized for use as a road base material, an aggregate in concrete and asphalt, railroad ballast, rip-rap, or fill.

1. Introduction. Self-curing (SC) concrete cures without external curing and polyethylene glycol (PEG) is one of the chemical agents that decreases water loss and pulls moisture from the surrounding environment, aiding in concrete curing Bashandy et al.

In this work, the effects of recycled concrete aggregate, modified with mineral admixtures and nanosilica, on the mechanical properties and performance of concrete after curing in tap water for 28 and 90 days were investigated. The compressive (ƒc), indirect tensile (ƒt), and flexural (ƒb) strengths for the cured concrete specimens This study investigated the sulfate resistance of Portland-dolomite cement (PDC) cured at different temperatures. Mortars of Portland cement (PC) and PDC with different dosages of dolomite, 10, 20, 30% by weight, were cured in water at 20 °C and 60 °C for 28 days before immersed in 50 g/L Na2SO4 solution at 20 °C.
