4、. Date Text affected National foreword This British Standard is the English language version of EN 1170-1 : 1997. The UK participation in its preparation was entrusted to Technical Committee B/524, Precast concrete products, which has the responsibility to: aid enquirers to understand the text; pres
5、ent to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. The UK voted against this standard at the CEN Formal Vote stage but the a
6、nalysis of voting, in accordance with CEN/CENELEC Internal Regulations Part 2 : Common rules for standards work, resulted in a positive vote. In consequence, the document was accepted as a European Standard. This standard, together with BS EN 1170 : Parts 2 to 7, supersedes BS 6432 : 1984 which is w
7、ithdrawn. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitl

23、lass-fibre reinforced cement without the fibres. It is made up of the mixture of sand, cement, water and any admixtures and additives. 3.2 Abbreviation GRC Glass-fibre reinforced cement. 4 Apparatus The apparatus comprises: a plastic or metallic tube, with a smooth internal surface, (55 0,5) mm high
24、 with an internal diameter of (57 0,5) mm and an external diameter of not less than 65 mm; a flat plate, of smooth, easily-cleaned material approximately (3003 300) mm on which are engraved, with a tolerance of 0,5 mm, nine numbered concentric circles, the diameters of which are given in table 1; a
25、trowel. 5 Procedure Put the plate on a horizontal support. Wipe the plate and the inside of the tube with a damp cloth. Put the tube on the plate, centering it in the engraved circle no. 0. Take about 200 cm 3 of the matrix ready to be used (for example from the pump hopper in case of spray). Fill t
26、he tube with matrix, wait a few seconds for the air bubbles to escape, and level the surface with the trowel. Lift the tube slowly and vertically. The matrix will spread out onto the plate. Wait approximately 30 s and read the number of the circle reached by the spreading matrix. If necessary, round
27、 the result to the nearest circle. Record the result in the test record book (an example of a record sheet is given in EN 1170-2). Clean and dry the apparatus. 6 Interpreting the result The optimum value is determined according to the method of manufacture and type of product to be produced. It is d
28、efined during the establishment of the mix design. If the result obtained does not comply with the optimum value defined, carry out a second test to validate the result before modifying the composition (e.g. change the water quantity).BSI 389 Chiswick High Road London W4 4AL | | | | | | | | | | | |
