Construction Aggregate Calculator. Enter the width, length, thickness, and product density and hit the "Calculate" button to calculate your estimate. If you do not know the product density, use the optional density estimator* or contact a local sales representative.

Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3) .

A primary consideration in the design of stable riprap bank protection schemes is the slope of the channel bank. For riprap installations, normally the maximum recommended face slope is 1V:2H. 7.9.3 Rock Size The stability of a particular riprap particle is a function of its size, expressed either in terms of its weight or equivalent diameter.

Riprap Characteristics • Layer thickness – the upper limit of D 100 – 1.5 times the upper limit of D 50 – Thickness should be increased by 50% if riprap is placed underwater – Oversized stones not contained within the prescribed layer can cause voids within the layer …
