{"product_id":"fosroc-conbextra-hf","title":"Fosroc Conbextra HF","description":"\u003cp\u003eFosroc Conbextra HF is a blend of Portland cement, graded fillers and chemical additives. The filler grading produces a highly flowable grout that will not segregate or bleed, and the low water requirement ensures high early strength and long-term durability. A volumetric expansion of up to 1% occurs while the grout is in the plastic state by means of a gaseous system, ensuring complete contact at the bearing interface. The product also conforms to the US Corps of Engineers Specification for non-shrink grout CRD-C621-82A and ASTM C1107-91 (Type C).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNon-shrink\u003c\/li\u003e\n\u003cli\u003eHighly flowable, will not segregate or bleed\u003c\/li\u003e\n\u003cli\u003eFire rating: Class A1 Non-Combustible\u003c\/li\u003e\n\u003cli\u003eSuitable for pumping\u003c\/li\u003e\n\u003cli\u003eComplies with London Underground Standard 1-085 (fire safety)\u003c\/li\u003e\n\u003cli\u003eCertified Carbon Neutral product\u003c\/li\u003e\n\u003cli\u003eInitial set: 6 hours\u003c\/li\u003e\n\u003cli\u003eGap thickness: 10mm to 100mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\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\u003eCompressive strength: 22 MPa at 1 day \/ 55 MPa at 7 days \/ 65–70 MPa at 28 days\u003c\/li\u003e\n\u003cli\u003eBond strength by pull-off: 2.6 MPa (EN 1542:1999, Class R4 ≥2.0 MPa)\u003c\/li\u003e\n\u003cli\u003eFlexural strength: 5.5 MPa at 28 days\u003c\/li\u003e\n\u003cli\u003eWater addition: 4.5 litres (flowable) \/ 4.8 litres (fluid) per 25kg bag\u003c\/li\u003e\n\u003cli\u003eYield: approx. 13.25 litres (flowable) \/ 13.5 litres (fluid) per 25kg bag\u003c\/li\u003e\n\u003cli\u003eTensile strength: 3.7 MPa at 28 days\u003c\/li\u003e\n\u003cli\u003eElastic modulus: 32.7 GPa at 28 days\u003c\/li\u003e\n\u003cli\u003eFreeze-thaw cycling: 2.4 MPa (Class R4 ≥2.0 MPa)\u003c\/li\u003e\n\u003cli\u003eChloride ion content: 0.04% (Class R4 ≤0.05%)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Fosroc","offers":[{"title":"Default Title","offer_id":57127675691340,"sku":"BM05955","price":19.85,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/fosroc-fosroc-conbextra-hf-1232467365.png?v=1776264274","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/fosroc-conbextra-hf","provider":"Construction Supplies UK","version":"1.0","type":"link"}
