Mechanical and physical properties of stabilised compressed coal bottom ash blocks with inclusion of lateritic soils in Niger

Mechanical, Thermal and Hydric Behavior of the Bio-sourced Compressed Earth Block (B-CEB) Added to Peanut Shells Powder

“…As for the density, the values of porosity of B-CEB corroborates with those reported in previous study, for PSP content less or equal to 20%. Lawane et al [38], in their study about the mechanical and physical properties of stabilized compressed coal bottom ash blocks with the inclusion of lateritic soils, have obtained a CEB characterized by porosity between 33 and 40%. Sore et al [9] reported the porosity of 37.63% for CEB stabilized with 15% of geopolymer.…”

Compressive Strength and Water Absorption of CSEB Mixtures. (Dept. C)

“…The increase in temperature reduced the cohesion property of the substances. The capillary absorption test is thought to be more realistic to evaluate the influence of rain and storms on the CSEB units, and was adopted by several researchers [12,20], consequently this test was used as the second technique to measure the absorption of the specimens. The test was conducted according to African Regional Standards for Compressed Earth Blocks ARS 674:1996 [19].…”

“…CSEB usually contains clay (non-expansive), silt powder, sand, water and a binding (stabilizing) material. The use of cement as a stabilizing material is common and in some cases lime can be used by itself [9,10] or can be used in combination with cement [10][11][12],. Any small variation in one or more of the ingredients of the mixture can significantly affect the properties of the produced units [4, 5, and 13].…”

Development of Cement Stabilised Compressed Blocks Using Coal Bottom Ash: Influence of the Grain Size on Mechanical and Physical Properties of Blocks

“…Vinai et al [16] showed that compressed blocks produced with a blend of laterite, BA and Portland cement could achieve average compression strength of 7 MPa, which is higher than the threshold recommended for compressed earth block by CRATerre, i.e., 4-5 MPa [17]. A partial substitution of cement with lime was also investigated in order to ascertain the possibility of reducing the environmental impact deriving from the use of Portland cement.…”
