Conbextra GPA is used to grout gap thicknesses of 50 – 200 mm. General pre-packaged non shrink cementitious grouts without aggregates are only suitable for gap thicknesses up to 100 mm. due to the high exothermic heat generation and the consequent risk of thermal cracking. Conbextra GPA contains aggregates that reduce this heat generation making it ideally suited to thick section grouting. In pockets, volumes of 100 litres can be achieved easily with Conbextra GPA. Typical applications of Conbextra GPA are:
- thick section voids beneath base plates
- voids around below-ground tanks
- large bolt pockets
مزایا:
- Non shrink and non metallic
- High compressive strength
- Resistant to impact from dynamic and repetitive loading
- No need to site batch aggregates
- Highly flowable
- Extended workability
- Can be pumped or poured
- Chloride free
