2014-2-11  While for cement stabilized soil there is considerable decrease in OMC 28% to 24% and increase in maximum dry density value of 12.83 KN/m3to 14.48 KN/m3. The results obtained from Unconfined Compressive Strength tests shown in table II indicate that the addition of lime and Ordinary Portland Cement to peat soil increases the Unconfined Compressive Strength values.

Behaviour of stabilised peat: A field study

2015-9-20  The aim of this study is to observe engineering behaviour of stabilised peat soil by deep mixing method using various types of binder. A field model study has been conducted to stabilise peat using various types of binder. Various mechanical properties of stabilised peat, like undrained shear strength, unconfined compressive strength and shear strength was determined after 14 days of curing time. Scanning electron micrograph (SEM) and energy dispersive x-ray (EDX) test were also conducted to observe the microstructure of stabilised peat soil. From the test result, it was observed that the engineering properties of peat soil can be improved bylight-weightstabilisationfill; usingand chemicaladditives.admixturesuch as cement

Effect of OPC and PFA cement on stabilised peat bricks

2014-1-6  The paper presents a study of compressive strength, water absorption and apparent porosity of different types of compressed stabilised peat bricks. Peat soil, sand, PFA cement or OPC cement were steam autoclaved under different conditions to produce brick samples. The percentage of peat soil 20%, PFA and OPC cement was between 20 - 30%, and sand ranged from 50 - 60%. The effect of each component of the mixtures on compressive strength, water absorption and apparent porosity of compressed stabilised peat after 3, 7, 14 and 28 days of conservation at 23 ± was 2°C. The compressive strength increased with increased binder ration. However, strength of mixture with PFA cement was higher than OPC cement. The water absorption decreased with increased ration of binder and period time. The apparent porosity decreased with increased period time. The compressive strength, water absorption and porosity of cemented peat bricks obtained at 28 days for both stabilisers PFA and OPC cement
