5.1 主要成分

道路用水硬粘结料的主要成分须从以下清单中选取：

• 符合 NF P 15-301：1994 标准第 4 条的成分：
  • 波特兰熟料（K）；
  • 粒状高炉渣（S）；
  • 火山灰料：天然白榴火山灰（Z）；
  • 粉煤灰：硅质粉煤灰（V）及钙质粉煤灰（W）；其粉煤灰的烧损可达 10.0%；
  • 钙质页岩（T）；
  • 石灰石（L）；
• 符合 NF P 15-311（CL、DL、HL、NHL）标准的石灰；

注：符合 NF P 15-301 标准的水泥及符合 NF P 15-307 标准的低标号水泥均可用作道路用水硬粘结料的成分，但条件是这两种水泥各自的成分要符合以上要求。

5.2 次要成分

添加次要成分是可以的，但不得超过总量的 5%。次要成分为特别挑选的天然矿料、熟料生产中产生的矿料、以氧气转炉烧炭冶金产生的炉渣，以及第 5.1 条中规定的成分 - 如果它们还没有被选用为道路用水硬粘结料的主要成分的话。

Foreword

This document (EN 10216-3:2002) has been prepared by Technical Committee EC/TC 29, "Steel tubes and fittings for steel tubes", the secretariat of which is held by UNI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.

ISO 657-1 : 1988 (E)

Table 1 — Dimensions and sectional properties of hot-rolled equal-leg angles (concluded)

NOTES

1. Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
2. For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
3. The sectional area has been calculated using the formula

   S = [l/2 A - l) + 0,214 6 (r_root² - 2r_toe²)] × 1/100

   where
   

   S is the sectional area, in square centimetres;
   

   l is the thickness, in millimetres;
   

   r_root is the root radius, in millimetres;
   

   r_toe is the toe radius, in millimetres;
   

   A is the leg length, in millimetres.

4. Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
