Description

Blocks are shlakobetonny. Company Budstroy, Nikolaev. Determine slag stone durability in vitro, using the necessary equipment for these purposes. When from the date of production 28 days expire, establish a sample for test on a press and press the top plate of a press. It is exposed to the increasing pressure up to its destruction. And strength of a sample at compression is calculated on a formula: Rszh = P/F, that is, P is an indicator of the greatest loading established during test of a sample, MN (kgf), and F – an indicator of cross-sectional area of a sample, (cm2). Respectively the calculated value will also be the easily soiled durability of slag stone. There is such concept as frost resistance of slag stone. It is meant as ability of slag stone to maintain in the humidified state without risk of destruction the repeated freezing alternating with thawing. The main reason for destruction of slag stone under the influence of low temperatures expansion of water which fills a slag stone time, in the course of freezing is considered. The indicator of frost resistance is influenced by t mainly structure of slag stone, namely, with increase in an indicator of relative volume of a time that are available to water penetration, frost resistance decreases. For the purpose of definition of degree of frost resistance use laboratory equipment and respectively establish it on the basis of laboratory research. The quantity of cycles "freezings — thawing" acts as an indicator (brand) of frost resistance up to loss as slag stone of 5% of weight or 25% of initial durability.
