density of recycled concrete

Apr 20, 2009 · It varies some depending on the density of you local aggregates used to make the concrete, and on your percentage of voids. For the product you're talking about here in my area I'd figure about 110-115#/cubic foot

crushed concrete aggregates - properties and uses of

3. Density The density of crushed concrete aggregate is smaller than natural aggregate density. 4. Water Absorption . Water absorption of recycled aggregate is greater than of natural aggregate. It is one of the most significant properties that distinguish recycled aggregate from raw aggregates

impact properties of recycled aggregate concrete with

Recycled aggregates were made from waste concrete beams and tested samples in the laboratory. The size ranged from 4.75 mm to 19 mm for RAC and nanosilica-modified recycled aggregate concrete (SRAC). Nanosilica sol solution was obtained by adding water in the sol, in …

recycled concrete - an overview | sciencedirect topics

Wet density of concrete was varied between 3.1% and 14.8%, hardened density between 3.5% and 14.1%, and oven dry density between 7.1% and 13.6%. Reduction of the density of air-dried concrete was lower and found to be in the range of 1.1%–12%

(pdf) mix design of recycled aggregate concrete using

This paper is devoted to the studies of material and mechanical properties of recycled aggregate concrete using packing density method. This paper considers mix of two different aggregate sizes of

mechanical properties of recycled aggregates concrete

Coarse recycled concrete aggregate (RCA) is produced by crushing sound, clean demolition waste of at least 95% by weight of concrete, and having a total contaminant level typically lower than 1% of the bulk mass. Other materials that may be present in RCA are gravel, crushed stone and hydraulic-cement concrete

WHY CHOOSE RECYCLED CONCRETE PRODUCTS? A. CDOT Class 6, Road Base Recycled Concrete: Lower unit weight. Modified proctor density = 120 lbs./cu. ft. = 1.65 tons/compacted cubic yard. This means better yield than that of local virgin bases. Advantage is typically 15% or greater

density of aggregate - bulk and relative density - civil

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 …

recycled concrete aggregates: its properties & uses

Density: Recycled concrete as aggregate contains residual adhered mortar on the particle of aggregate. Due to which the density of RCA is normally lower than the density of natural aggregate

concrete mix design for completely recycled fine aggregate

As the compacted bulk density of 1 m 3 of the aggregate mixture at this proportion is 1835 kg/m 3, the content of the CRFA, crushed aggregate 1, and crushed aggregate 2 in 1 m 3 of the concrete is equal to 734, 220, and 881 kg/m 3, respectively

recycled aggregates - portland cement association

Recycling of concrete is a relatively simple process. It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality. See ACI 555 (2001) for more information on processing old concrete into recycled concrete aggregates
