The result shows that the flexural strength of cement mortar reduces greatly by adding hydroxyethylmethylcellulose, while adding vinyl co-polymer the strength can increase considerably.
The adhesion strength of hydroxyethylmethylcellulose modified mortar and ethylene copolymer modified mortar were studied at different curing condition.
