Evaluation of Concrete Grinding Residue (CGR) as a Soil ...

Concrete diamond-grinding work on pavement projects generates a non-hazardous waste by-product called concrete grinding residue (or CGR). CGR has known cementitious characteristics that suggest a latent use as a soil-stabilizing amendment, especially for poor and problematic soils. In this study, Western Iowa loess soil was amended with CGR and ...

Compaction and Root Modifications of Soil Aeration -

This study was designed to measure plant root and soil aeration interactions with soil compaction. A clay soil was compacted to bulk densities in 1.1, 1.4 and 1.7 Mg m-3 in soil columns planted to dry edible bean. Oxygen diffusion rates (ODR) were below the critical level for the 1.7 Mg m-3 treatment at all plant growth stages measured.

Two Common Compaction Mistakes, and How to Avoid …

Over compaction will cause the soil to break down which reduces its support capability because of the separation that occurs within the soil mix itself. This leads to weakness, not strength. Think of it like this; if you have a pile of small rocks and you want to hammer them down flat, you can do so with the right amount of force.

What is sand? Composition & Types of Sand - Civil Engineering

Sand is a mixture of small grains of rock and granular materials which is mainly defined by size, being finer than gravel and coarser than silt. And ranging in size from 0.06 mm to 2 mm.Particles which are larger than 0.0078125 mm but smaller than 0.0625 mm are termed silt.. Sand is made by erosion or broken pebbles and weathering of rocks, which is carried by seas or rivers.

Soil compaction | UMN Extension

What is compaction? Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores more effectively move water downward through ...

Swell Factors for Various Soils - ProjectEngineer

Swell Factors for Various Soils. A cubic yard of earth measured in its natural position swells to more than a cubic yard after it is excavated. This occurs because of an increase in voids. Swell is expressed as a percentage of natural volume, for example, if 10 yd 3 in the ground becomes 13 yd 3 after excavation, the swell factor is 30%.
