| Abstract: | The effect of eight commercial superplasticizers including one developed from Cashew Nut Shell Liquid (CNSL) at CBRI on the rheological properties viz. viscosity and flow of cement paste and mortars have been investigated. The viscosity measurements have been made at various shear rates (5 -100 rpm). It is found that at higher rates
(100 rpm) even with the low concentration of superplasticizers (0.1), the viscosity of 'the cement paste is more or less same as that obtained with 0.6 % dosages of SPs at lesser shear rates. The effect of split addition (delayed addition) of superplasticizers on viscosity of cement paste and 1:3 cement sand mortar have also bee~ studied, A decrease in viscosity due to split addition has been observed in the cement paste and there is an increase of 15-20 % in flow of mortars. |
