(PDF) Stabilization of peat by deep mixing method: A ...

When a method of deep mixing is choosen, water content of unstabilized soil is to be considered. As the soil already has a high water content, required water for soil-cement reaction comes from the soil. So Dry Jet Mixing (DJM) method is effective for peat soil stabilization instead of Wet Mixing method.

About Deep Soil Mixing - Soil Stabilisation, ground ...

THE DEEP SOIL MIXING TECHNIQUE. Deep soil mixing is an in situ ground improvement technique that enhances the characteristics of weak soils by mechanically mixing them with a cementitious binder. The action of mixing materials such as cement, fly ash, lime or bentonite with soil causes the properties of the soil to become more like soft rock.

There are two large groups of cacti grown as houseplants; both are popular and familiar, and both can thrive indoors with relatively little maintenance. If you have the choice, use Vermiculite over Perlite when you have houseplants which need a lot of watering. If you do use coffee grounds on your indoor plants, either directly or as part of a compost, you can reduce the risk of overwatering ...
