Step 4: Calculate Sand Quantity. Since the mix is 1:1.5:3 for cement:sand:aggregate, the quantity of sand will be determined just as in the case of cement but using the sand ratio. Quantity of Sand = (1.5 / 5.5) × 1.52 = 0.414 m³. Convert this volume to weight, because 1 m³ of sand = 1600 kg. Sand in kg = 0.414 × 1600 = 662.4 kg

Aggregate is an important raw material in the infrastructure construction industry. Aggregate is divided into fine aggregate (commonly known as sand, with a particle size between 0.15-4.75mm) and coarse aggregate (commonly known as stone, with a particle size between 4.75-9.0mm).. The aggregate material is loose and granular in shape and is the basic raw material …
How Aggregate Processing Works. Aggregate processing can include many different steps depending on the specific material desired. However, all aggregate processing includes two steps: extraction and screening. Most aggregate processing also involves crushing. Aggregate Extraction. The first step in aggregate processing is extraction.
