SikaCem®-810

Modified SBR Polymer Admixture

SikaCem® 810 is a One Component modified SBR polymer ,blended with plasticisers and selected fillers. When diluted it produces a gauging solution for improving cementitious mixes.

  • Improved Workability
  • Improved Mechanical Properties, such as Abrasion and Impact
  • Improved Resistance to Freeze / Thaw Cycles
  • Reduced Shrinkage and Cracking
  • Reduced Permeability
  • Chloride Free
  • Enhanced properties over unmodified SBR and Acrylic Resins

Adhesion strength can be improved by using Sikadur® 32 Normal or SikaTop® Armatec 110 EpoCem® as a bonding coat.
Adhesion strength will be dependent on conditions of substrate, preparation, techniques and application.
Final mechanical properties will be dependent on temperature, aggregate / sand type, moisture content and curing regime
More accurate information regarding workability, mechanical strengths and strength gains should be obtained from site trials and appropriate strength / adhesion tests
Where Increased open times and adhesion strength are required for bonding coat / slurry use Sikadur® 32 Normal or SikaTop® Armatec 110 EpoCem®

Application steps

MIXING

SikaCem® 810 must be mechanically mixed using a forced action mixer or in a clean drum using a drill and paddle (max. 500 rpm). A normal concrete free fall mixer is NOT suitable.
Mix SikaCem® 810 with clean water to produce a gauging solution in the correct ratio for 90 seconds. Add gauging solution to cement / aggregate mix until desired consistency is achieved

CLEANING OF TOOLS

Clean all tools and application equipment with clean water immediately after use. Hardened / cured material can only be removed mechanically.
