Adopts EAS 18-1-2017·EAS

This East African Standard gives the specifications which include mechanical, physical and chemical requirements of 27 distinct common cements, seven sulphate resisting common cements as well as three distinct low early strength blast furnace cements and two sulphate resisting low early strength blast cements and their constituents.The Standard also gives the composition of each cement in terms of propotions and requirements of the constituents which are to be combined to produce these distinct products in a range of nine strength classes. Furthermore this standard states the conformity criteria and related rules. Necessary strength durability requirements are also given.

Adopts EAS 18-2-2017·EAS

This East African standard specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements to their corresponding product specification standards, including certification of constancy of performance by a product certification body.This standard provides technical rules for factory production control by the manufacturer, including auto- control testing of samples, and for the tasks of the product certification body. It also provides rules for actions to be followed in the event of non-conformity, the procedure for the AVCP and requirements for dispatching centre.

Adopts EAS 73:2000·EAS

This East African Standard specification applies to quick and hydrated lime intended for use in buildings.

Adopts EAS 148-1-2017·EAS

This East African Standard describes the method for the determination of the compressive and, optionally, the flexural strength of cement mortar. The method applies to common cements and to other cements and materials and is used for assessing whether the compressive strength of cement is in conformity with its specification and for validation testing of standard sand, or alternative compaction equipment. This standard describes the reference equipment and procedure and allows alternative compaction equipment and procedures to be used provided that they have been validated in accordance with the appropriate.provisions in this standard. In the event of a dispute, only the reference equipment and procedure are used

Adopts EAS 148-2-2017·EAS

This East African standard specifies the methods for the chemical analysis of cement. The East African Standard describes the reference methods and, in certain cases, an alternative method which can be considered to be equivalent. In the case of dispute, only the reference methods are used.The East African Standard also describes methods which apply principally to cements, but which can also be applied to their constituent materials and other materials

Adopts EAS 148-3-2017·EAS

This East African Standard specifies the methods for determining standard consistence, setting times and soundness of cements. The method applies to common cements and to other cements and materials.This East African Standard describes the reference methods and allows the use of alternative procedures and equipment provided that they have been calibrated against the reference methods

Adopts EAS 148-4-2017·EAS

This East African standard describes the procedures for determining the contents of the most of the constituents of cements that fall within the scope of EAS 18- 1

Adopts EAS 148-5-2017·EAS

This East African standard specifies the method of measuring the pozzolanicity of pozzolanic cements conforming to EAS 18-1. This East African Standard does not apply to Portland pozzolana cements or to pozzolanas

Adopts EAS 148-6-2017·EAS

This East African standard describes three methods (sieving, air-jet and air permeability methods) for determining the fineness of cement and applies to all the cements defined in EAS 18- 1.

Adopts EAS 148-7-2017·EAS

This East African Standard describes the equipment to be used, the methods to be followed and the provisions to be complied with for taking samples of cement representative of given lots for testing to assess the quality of products prior to, during or after delivery. The provisions of this East African Standard are only applicable when samples of cement are requested for verifying the compliance

Adopts EAS 148-8-2017·EAS

This East African standard lays down the methods for determining the heat of hydration by means of solution calorimetry, also known as the solution method. The heat of hydration is expressed in joules per gram of cement. This East African Standard is applicable to cements and hydraulic binders whatever their chemical composition
