Abstract
Official abstract text for this publication.
The present invention relates to methods for providing modified cement compositions having increased slip resistance and/or a decreased setting time in comparison to cement compositions comprising from 1 to 10 weight percent redispersible polymer powder (RDP) and water soluble cellulose ether in a specific amount from 0.1 to 1.0 weight percent, based on the total dry weight of said composition. Also provided are dry mortars comprising cement, RDP, water soluble cellulose ether and one or more additives selected from gelatin, bentonite and combinations thereof for use in such methods, and cement-free mixtures comprising water soluble cellulose ether and one or more additives selected from gelatin, bentonite and combinations thereof which may be added to cement binder for use a for use in such methods.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for providing a modified cement composition to improve its slip resistance, said method comprising: a) forming a dry mortar composition comprising: i. cement; ii. from 1 to 10 weight percent redispersible polymer powder; iii. water soluble cellulose ether in an amount of X minus Y, wherein X is from 0.1 to 1.0 weight percent of the composition; and iv. gelatin, in a total amount Y, wherein Y is from 0.02X to 0.30X; and b) combining s…
