标准简介

OVERVIEW

中文简介

该标准规定了建筑石灰的试验方法,包括取样、化学分析(如氧化钙、氧化镁、二氧化碳含量)以及物理性能测试(如抗压强度、细度、安定性、凝结时间等)。它适用于建筑石灰的定义、规格及符合性评估中的测试环节,是EN 459系列标准的重要组成部分。

English summary

This standard specifies test methods for building lime, including sampling, chemical analysis (such as CaO, MgO, and CO2 content), and physical tests (such as compressive strength, fineness, soundness, and setting times). It applies to the testing phase of building lime definitions, specifications, and conformity assessment, serving as a key component of the EN 459 series.

3 Sampling

3.1 General

Sampling shall be carried out as specified in 3.1 to 3.4 taking into account the need to minimize moisture and carbon dioxide absorption.

3.2 Sampling of powdered material

Sampling shall be carried out in accordance with EN 196-7.

Before carrying out chemical analysis, the sample shall be reduced in mass by means of a sample divider and/or by quartering to produce a sub-sample of suitable mass for the intended determinations. Any coarse material shall be reduced in size to less than 0,3 mm.

3.3 Sampling of granular material

Sampling shall be carried out in accordance with EN 932-1.

Before carrying out chemical analysis, the sample shall be crushed, ground and reduced in mass to produce a sub-sample finer than 0,3 mm and of suitable mass for the intended determinations.

3.4 Sampling lime putties

The spot sample size shall be (10 ± 5) dm3.

Where lime putties are sampled, the increments shall be blended thoroughly.


1) EN 196-21 is currently being incorporated into EN 196-2.
