Cement – Part 1: Common cement – Performance assessment and declaration
Abstract
This document covers calcium silicate cement (common cement) intended to be used: — for the preparation of concrete, mortar, grout, and other mixes for construction and for the manufacture of construction products including structural and non-structural products, including white cement; — for the preparation of mortar for bricklaying, blocklaying, rendering and plastering, including white cement; — for the preparation of adhesives for other construction products; — for soil stabilisation or improvement, road bases and sub-bases, and capping layers. Calcium aluminate cement, supersulfated cement, very low heat cement and alkali activated binder as well as masonry cement exclusively manufactured for the preparation of mortar for bricklaying, rendering and plastering are excluded from this product definition. Note Calcium silicate cements with an intended use as defined in this document belong to the product category "common cement". The product definition of common cement covers the following combination of constituents expressed in percentage as mass, any other combination is outside the product definition: (a) primary cement (minimum of 95% clinker); Note 1 This refers to the designation code CEM I. (b) binary cements with clinker and a maximum of 95% of blast furnace slag; Note 2 This refers to the designation codes CEM II/A-S, CEM II/B-S, CEM III/A, CEM III/B, CEM III/C. (c) binary cements with clinker and a maximum of 10% of silica fume; Note 3 This refers to the designation code CEM II/A-D. (d) binary cements with clinker and a maximum of 35% of one of the following constituents: natural pozzolana, natural activated pozzolana, fly ash, coal bottom ash, burnt shale, limestone or recycled concrete fines; Note 4 This refers to the designation codes CEM II/A-P, CEM II/B-P, CEM II/A-Q, CEM II/B-Q, CEM II/A-V, CEM II/B-V, CEM II/A-W, CEM II/B-W, CEM II/A-Z, CEM II/B-Z, CEM II/A-T, CEM II/B-T, CEM II/A-F, CEM II/B-F, CEM II/A-L, CEM II/B-L, CEM II/A-LL, CEM II/B-LL. (e) pozzolanic cements with clinker and a maximum of 55% of a combination of silica fume, natural pozzolana, natural activated pozzolana, fly ash and coal bottom ash with a maximum of 10% silica fume; Note 5 This refers to the designation codes CEM IV/A, CEM IV/B. (f) composite cement with a minimum of 50% of clinker, a maximum of 29% of recycled concrete fines and a maximum of 44% of any combination of blast furnace slag, silica fume, natural pozzolana, natural activated pozzolana, fly ash, coal bottom ash, burn shale and limestone with a maximum of 10% silica fume and a maximum of 35% of the aggregation of limestone and recycled concrete fines; Note 6 This refers to the designation codes CEM II/A-M, CEM II/B-M, CEM II/C-M (containing recycled concrete fines and other allowed constituents). (g) composite cement with a minimum of 50% of clinker and a maximum of 50% of any combination of blast furnace slag, silica fume, natural pozzolana, natural activated pozzolana, fly ash, coal bottom ash, burnt shale, limestone and recycled concrete fines with a maximum of 10% of silica fume, a maximum of 20% of recycled concrete fines, and a maximum of 35% of any combination of limestone and recycled concrete fines; Note 7 This refers to the designation codes CEM II/A-M, CEM II/B-M, CEM II/C-M (containing allowed constituents). (h) composite cements with a minimum of 20% of clinker, a maximum of 49% of blast furnace slag and a maximum of 49% of a combination of natural pozzolana, natural activated pozzolana, siliceous fly ash and coal bottom ash; Note 8 This refers to the designation codes CEM V/A, CEM V/B. (i) composite cements with a minimum of 35% clinker, a maximum of 59% of blast furnace slag and a maximum of 20% of natural pozzolana, natural activated pozzolana, siliceous fly ash, coal bottom ash, limestone or recycled concrete fines; Note 9 This refers to the designation codes CEM VI/A (S-P), CEM VI/A (S-Q), CEM VI/A (S-V), CEM VI/A (S-Z), CEM VI/A (S-F), CEM VI/A (S-L), CEM VI/A (S-LL). (j) composite cements with a minimum of 21% clinker, a maximum of 49% of blast furnace slag and a maximum of 49% of limestone. Note 10 This refers to the designation codes CEM VI/B (S-L), CEM VI/B (S-LL). All the above combinations can contain — up to 5% of a minor additional constituent (A.1) as long as the same constituent is not used as a main constituent; minor constituents are specially selected, inorganic natural mineral materials and inorganic mineral materials derived from the clinker production process; — calcium sulfate (A.2) to control setting; — additives (A.3) up to 1,0% to improve the manufacture or the properties of the cement. Note 11 The proportions indicated take into account the constituents of cement, both main and minor, and not the other permitted components. In the common cement, the other components authorized in addition to a combination of constituents are calcium sulphate to control setting and additives to improve the manufacture or the properties of the cement.
