Local Aggregate in Production of Concrete Mix in Jordan

Abstract

Concrete properties such as unit weight and compressive strength are highly dependable on the properties of aggregate. Current research aims to study the effect of aggregate properties on concrete considering the resource of aggregate. The properties of aggregate and fine sand were studied (specific gravity, density, absorption, and abrasion). Also, the properties of concrete were studied (density, unit weight, and compressive strength). Samples of coarse and medium aggregates, and fine sand were collected from different areas in Jordan (Ajloun,

Testing the Use of Rounded Valley Aggregate in Concrete Mix in Comparison with Crushed Limestone Aggregate

“…Since aggregate composes about 75% of concrete volume, aggregate affects the properties of concrete [16]. The shape of aggregate affects concrete workability in fresh stage and compressive strength in hardened stage and finally durability of concrete [2].…”

Use of Magnesium-Containing Mining Waste

“…Обычно в качестве крупного заполнителя используются гранит и гравий. В ряде статей рассматривается возможность замены их известняком и песчаником, однако марочная прочность полученных бетонов не превышает показатели бетонов на гранитном щебне [4,5]. Положительное влияние на механические показатели бетонов оказывает замена традиционного заполнителя кварцитом, диабазом, базальтом [6][7][8].…”
