Effect of Selected Pre Treatment on Setting of Cement Composite from Two Rattan Species.
Abstract
The effects of aqueous extraction and removal of vilified epidermis from rattan canes on the maximum hydration temperature (Tmax) and settling time (tmax) of two rattan cane species, Calamus deerratus and Lascosperma secundiflorum, mixed with Portland cement were investigated. Max ranged from 37.0 to 58.6oC and from 43.1 to 56.8oC for the C. Detritus and L. secundiflorum composites respectively while tmax was from 3.7 to 26.5 hrs and 7.4 - 25.7 hrs. Aqueous extraction increased the Tax and reduced bite the tmax of the rattan-cement mixes while removal of epidermis generally caused reduction in both Tmax and tmax. The two rattan species seemed more amenable to cold than hot water extraction. Although cement inhibition of the Calamus species was greater than that of Lacosperma species, aqueous extraction improved the tmax of the Calamus-cement composite more than Lacosperma-cement composite. Epidermis removal, species, aqueous pre-treatment and their interactions had significant effect on the setting time of the rattan-cement mixes.
