Effects of crushed stone dust on some properties of concrete
Crushed rock dust acts as a filler and helps to reduce the total voids content in concrete. Consequently, this contributes to improve the quality of concrete. In v FOREWORD Aggregates from crushed rocks are in general flakier and have a rougher surface than natural aggregates. This leads to an increased cement demand. To avoid IMPACTS OF USING CRUSHED ROCKS IN CONCRETE DiVA

(PDF) INVESTIGATION OF ROCK AGGREGATE QUALITY
Compressive strength is the most vital property of a concrete. The textural and mineralogical features of rocks also have substantial impacts Based on the crushability tests, crushedAccording to the main objectives of the research, the following scheme has been implemented for the research method (Fig. 2). Different types of rocks were collected from different quarries of Iran, Isfahan. Then, they were crushed by two types of rock crusher. The produced aggregates were studied for shape characteristics.The effect of rock crusher and rock type on the aggregate shape

with river sand is more malleable than the CSB concrete and CSG concrete. Besides the technical aspect, due to the cost of transport and the scarcity of river sand, concretes made with alluvial sand is more costly (49.893 FCFA/m3 of concrete) compared to concretes made with crushed gneiss and basalt costing 47.053 FCFA and 46.854 FCFA/m3,The mining industry manages large volumes of tailings, sludge, and residues that represent a huge environmental issue.

(PDF) Effect of Local Coarse Aggregate Type on Concrete
Crushed river gravel, trap rock, dolomitic limestone, and calcitic limestone were used in high-performance concrete (HPC) production in varying amounts: 36, 40, and 44 percent by concrete volume.maximum tensile strength of concrete is obtain at 60% and 70% replacement of natural sand with Crushed sand. The concrete with crushed sand performed better than concrete with natural sand as the property of crush sand is better than that of natural sand.

Compressive strength of concrete is believed to have a large impact on the energy required for crushing concrete, based on the similar findings for crushing rocks (natural stone) (Korman et alThe moisture content of crushed rocks, sand and rubber aggregates was 0.074, 1.38, and 0.78%, respectively, which was considered during the mix design process to adjust the water content.

The Deformation Characteristics and Lateral Stress of Roadside Crushed
Gob-side entry retaining formed by roof fracturing (GERRF) is a popular non-pillar mining method. The method uses crushed rocks in gob side to support and control the movements of the gob roof. These crushed rocks will deform under roof pressure and generate desirable lateral stress on support structures of gangue rib. In this This paper examines the effect of the aggregate type on concrete strength, and more specifically, how the petrographic characteristics of various aggregate rocks as well as their physico-mechanical properties influences the durability of C 25/30 strength class concrete. The studied aggregate rocks were derived from Veria-Naousa Minerals Free Full-Text The Effect of Petrographic Characteristics

Crushed Concrete Driveway Pros and Cons
The cost of gravel ranges from just $1 to $2 per square foot, while crushed concrete can run as low as $0.60 for the same. For a 400-square-foot driveway, you could pay as little as $240 for materials. Compare this to the cost of installing a concrete slab —which is an average of $6 per square foot —and you quite the savings.Xia et al. investigated the dynamic compressive strength, impact toughness, and fragmentation size distribution law of the plain concrete and the carbon nanofiber reinforced concrete with 0.1%, 0.2%, 0.3%, and 0.5% volume content.
