“…The addition of natural fiber such as date palm fibers will increase the total water absorption of CEB (Taallah et al, 2014). Figure 17.4 indicates that longer immersion times will cause higher total absorption.…”

“…Additional of natural fiber content such as palm date fibers will decrease the tensile strength with the increase of fiber content, but only causes a slight reduction in compressive strength (Taallah, Guettala, Guettala, & Kriker, 2014). However, the addition of natural fiber has unfavorable results on wet compressive strength of the CEB.…”

“…The growing environmental concerns have led to the discovery and appreciation of the unique qualities of earth materials. The use of earth material in construction works, will not lead to depletion of resources, increased pollution (water, air, soil), waste generation and biological changes (Bachar et.al., 2015) Researchers have proposed tropical soils as a sustainable resource to be utilised in the construction of housing around the world (Houben and Guillaud 1994;Rigassi 1995;Arumala 2007;Oti et al 2009b;Oti et al 2009a;Das et al 2010;Deboucha and Hashim 2011;Goodary et al 2012;Villamizar et al 2012;Bachar et al 2014;Taallah et al 2014). Laterite as a typical tropical soil that could fill the gap between a housing deficit and provision of modest housing for the growing populations in Africa.…”

Lateritic soils which have been described as highly weathered tropical or sub-tropical residual soils, were studied with an attempt to establish its suitability or otherwise as sustainable material in building bricks and housing development that will meet the present challenge of sustaining the environment without costing too much and maintaining a high standard of strength, durability and aesthetics. Index properties of the tested lateritic soils revealed them as mostly well-graded, comprising both cohesive (silt and clay) and cohesionless (sand and gravel) soil fraction. The geotechnical analyses on the studied lateritic soil revealed a strong compressive strength with a relatively sound dry density which could guarantee a good durability in resulting bricks made from these soil materials.Further test on the strength and durability of the compressed earth bricks (CEBs) made from these lateritic soils revealed a brick with compressive strength ranging between 6.33 and 15.57 MPa which are considered to be good strength coupled with its sound durability strength established over a period more than one year under a complete cycle of weather and seasonal conditions.In conclusion, lateritic soils from the study area were found to be suitable as materials for bricks (CEB) with good compressive and durability strength which qualifies them sustainable and cost effective materials for lowcost housing development.

“…The volumes of fibers within the blocks were relatively low, especially when compared to research with natural fibers (Taallah et al 2014). The degradation observed with the fiber reinforced CEBs was consistent across the entire block, and not focused around regions of fiber exposure.…”

“…It was also thought that the addition of fibers to CEBs would decrease their density (Taallah et al 2014), which may impact their durability and strength. For these reasons, absorption and density tests were performed following ASTM C140 -Sampling Where Abs is the CEB absorption measured in %, Wt SSD is the saturated surface dry weight, W OD is the oven dry weight, W Sub is the submerged weight and UW Water is the unit weight of water.…”

The Effect of Clay, Cement and Fibers on the Strength and Durability of Compressed Earth Blocks

This Thesis examines the effect of soil characteristics, cement content and fibers on the strength and durability of compressed earth blocks (CEBs). This work expands on the available information regarding the constituent properties which affect the compressive and tensile strengths and durability of CEBs. Additionally, little research on the subject of synthetic fibers and their effect on strength and durability of CEBs is available and this work provides an initial study in this area.To study the effects of fibers, as well as confirm the trends of previous research regarding the effects of clay and cement, 27 unique batches of CEBs were pressed and tested using a Vermeer BP 714 block press. Three different soil types and two fiber types were utilized. The compressive strength, modulus of rupture (MOR), absorption, and durability were measured on over 185 specimens. The strength and absorption tests were adapted from common ASTM International test methods for similar materials, while the durability test was a uniquely developed method to quantify durability by measuring mass loss during drying and wetting cycles.After the testing regimen was completed, a trend between clay content and strength could not be determined. Durability testing suggested that as clay content decreases, durability increases. A linear relationship was found between cement content and strength, which was confirmed during durability testing. The addition of different fibers did not have an effect on the peak strength of CEBs, although it appears they may decrease the durability. The gross versus net unit strengths of CEBs were examined due to the unique shape of the CEBs utilized. Additionally, a mathematical expression relating the MOR to the compressive strength was developed.
