TWO-CAVITY MOULD FOR PRODUCTION OF PILOT SAMPLES OF CONCRETE

摘要

FIELD: procedure of test of materials, in particular, production of concrete pilot samples. SUBSTANCE: installed in the double-cavity mould in the point of attachment of the partition is a rigid filter of polymeric material with a high filtering capacity, which allows moisture freely move from one half of the mould to the other at removal of the metal partition. EFFECT: construction of a mould for production of concrete pilot samples providing for consideration of soil-dampness conditions of hardening of concrete of cast-in-place piles, maximized correspondence of strength characteristics of concrete of pilot samples to the strength of concrete in the pile shaft. 3 dwg
