{"product_id":"fosroc-conbextra-uw","title":"Fosroc Conbextra UW","description":"\u003cp\u003eFosroc Conbextra UW's aggregate grading minimises segregation and bleeding whilst maintaining flow characteristics, and the gaseous expansion system compensates for shrinkage and settlement in the plastic state. When placed above water it can be used in section thicknesses up to 75mm in a single pour; when placed underwater, the heat-sink effect of the environment allows thicknesses of up to 150mm. For thicker sections, Conbextra UW can be extended with clean rounded well-graded aggregate at a ratio not exceeding 1:1 by weight — allowing sections up to 200mm above water and up to 400mm underwater.\u003c\/p\u003e\n\u003cp\u003eTypical applications include; s\u003cspan style=\"font-size: 0.875rem;\"\u003etanchion baseplates in submerged or tidal conditions, b\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eridge columns and quay pillars and c\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eoncrete piling and slipways\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWash-out resistant, no significant cement phase loss in stationary or moving water\u003c\/li\u003e\n\u003cli\u003eDisplaces water effectively\u003c\/li\u003e\n\u003cli\u003eNon-shrink \u003c\/li\u003e\n\u003cli\u003eChloride free \u003c\/li\u003e\n\u003cli\u003eCan be poured or pumped\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh early and ultimate strength — 25 MPa at 1 day \/ 50 MPa at 7 days \/ 60 MPa at 28 days\u003c\/li\u003e\n\u003cli\u003eExceptional freeze-thaw resistance: 2.1 MPa (Class R4 ≥2.0 MPa)\u003c\/li\u003e\n\u003cli\u003eBond strength by pull-off: 2.2 MPa\u003c\/li\u003e\n\u003cli\u003eElastic modulus: 30.7 GPa at 28 days\u003c\/li\u003e\n\u003cli\u003eSection thickness above water: 10mm to 75mm (up to 200mm with aggregate extension)\u003c\/li\u003e\n\u003cli\u003eSection thickness below water: up to 150mm (up to 400mm with aggregate extension)\u003c\/li\u003e\n\u003cli\u003eWater addition: 5.5 litres per 25kg bag (flowable)\u003c\/li\u003e\n\u003cli\u003eYield: approximately 14.5 litres per 25kg bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Fosroc","offers":[{"title":"Default Title","offer_id":57127675461964,"sku":"BM05952","price":37.13,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/fosroc-fosroc-conbextra-uw-1232467368.png?v=1776264334","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/fosroc-conbextra-uw","provider":"Construction Supplies UK","version":"1.0","type":"link"}
