Shariful Islam M., Elahi T., Shahriar A. R., Mumtaz N.,  Effectiveness of fly ash and cement for compressed stabilized earth block construction, Construction and Building Materials, vol. 255. HighlightsSuitability of  Compressed Stabilized Earth Block (CSEB) stabilized with cement and fly ash is assessed in terms of strength and durability.Inclusion of fly ash is effective in reducing the cement content significantly.Optimum fly ash content is 15% for 5–7% cement content.Fly ash is effective in reducing water absorption capacity.Fly ash and cement stabilized CSEBs are more suitable compared to fired clay bricks from economic standpoint.AbstractFor  saving natural resources, reducing pollution and increasing energy  efficiency, Compressed Stabilized Earth Block (CSEB) can serve as a  suitable alternative to conventional Fired Clay Brick (FCB). In this  study, suitability of industrial waste, Fly Ash (FA) is assessed along  with cement as stabilizers for producing CSEBs with coarse grained soil.  Different combination of cement and FA (5–10% cement and 5–25% FA; by  weight of dry soil) was considered to prepare CSEBs for finding the  optimum mix composition in terms of strength, durability, deformation characteristics and cost effectiveness. Furthermore, strength and  durability test results are compared to the design criteria reported in  Indian Standard, Sri Lankan Standard, Standard Australia, British  Standard and Malaysian Standard for assessing its viability as  construction material. With the increase in cement content, strength of  the blocks gradually increases; however, at a definite cement content,  addition of FA increases strength up to a certain limit and then begins  to drop. Inclusion of 7–8% cement and 15–20% FA is found to provide  adequate dry compressive strength (&#62;5 MPa), wet-to-dry compressive  strength (&#62;0.33) and enough durability in terms of water absorption  (&#60;20%) as recommended by British Standard and Standards Australia.  The behavior of the CSEBs were also analyzed through microstructural  investigation, where SEM images were taken to ascertain the morphologic  and anatomic changes that occurred at different fly ash contents. At a  definite cement content, with the increase of FA, peak strain and  failure strain increase; thereby indicating an improved straining  capacity of the blocks due to inclusion of FA. Moreover, modulus of  elasticity improves with increasing amount of cement and FA for both dry  and wet state. Furthermore, economic analysis of a typical house  constructed with CSEBs and FCBs was performed and compared with  literature. Considering all the parameters it can be concluded that  CSEBs prepared with cement and fly ash as stabilizers can be used as a  sustainable construction material.Info: https://www.sciencedirect.com/science/article/abs/pii/S0950061820313970
