With concrete being one of the most useful building materials, there are countless applications for its use on-farm. The most common uses of concrete are for shed floors and footings, bunkers, post footings and stockyards. While the process of laying concrete can be expensive, there are several options for those wishing to carry out the work themselves and save money.

The research can be found in a paper titled “Sustained Service-Load Behavior of Concrete Beams with Recycled Concrete Aggregates,” accepted and soon to be published by ACI Structural Journal.

Recycled Concrete Aggregate - an overview ScienceDirect ... However as shown in Chapter 5 there is a greater probability of recycled masonry aggregates (RMAs) showing higher water absorption capacity compared with RCA and thus for a given replacement level the former is more likely to produce concrete exhibiting greater permeability and sorptivity than the latter (Soutsos et al. 2011; Gomes ...

Apr 01, 2020 · After casting for 1 day, the concrete specimens were cured in water, and divided into 3 groups: (i) conventional concrete (CT concrete) is the concrete composed of natural aggregates (crushed limestone and river sand), (ii) RA concrete is the concrete composed of river sand and R-CA, including GBA was used to substitute OPC at 20 to 50%wt of ...

May 14, 2015 · This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete.

of recycled aggregate in concrete prior to 1996, it was from 1996 until 2002 that the main knowledge base on use of recycled concrete aggregate (RCA) was formed since at that time these materials reflected the highest and most consistent quality of all recycled aggregates available. Mobile crushers whilst often more economical

This study evaluated the use of recycled concrete as coarse aggregate in new concrete pavements. Recycled concrete aggregate (RCA) produced from demolished pavements in three geographically-dispersed locations in Washington state were used to perform testson aggregate characte ristics, fresh concrete propertiesand hardened concrete properties.
