-天然沙子来源的减少和降低混凝土生产成本的要求，导致在混凝土生产中，特别是在混凝土中，越来越需要确定沙子的替代材料作为细骨料。采石场粉尘是采石活动过程中粉碎过程中产生的副产品，就是这种材料之一。花岗岩粉或石粉是花岗岩粉碎过程中产生的副产品，也称为采石场粉尘。最近几天，也有许多人尝试使用工业副产品飞灰作为水泥的部分替代品，以具有更高的工作性和长期强度，并使混凝土更经济可行。本工作是利用采石场粉尘部分替代混凝土中砂的一种尝试。人们试图研究混凝土的性能，并研究石矿粉的一些特性，以及这些特性的适用性，以使它们能够用作混凝土中的部分砂子替代材料。
-The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials. Granite fines or rock dust is a by-product obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available. This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete. Attempts have been made to study the properties of concrete and to investigate some properties of Quarry Dust the suitability of those properties to enable them to be used as partial replacement materials for sand in concrete.
