On the hygrothermal properties of sandcrete blocks produced with sawdust as partial replacement of sand

In Nigeria, sawdust is continuously generated in large quantities as waste but majorly under-utilised, a situation which causes serious environmental problems and health hazards when managed improperly. This work focussed on production and assessment of hygrothermal properties of solid core sandcret...
