ISO 1920-2:2016规定了新拌混凝土的测试程序。它规定了以下试验方法:稠度测定(坍落度试验、Vebe试验、压实度、高流动性混凝土的流动台试验和坍落度流动试验)、新鲜密度测定和空气含量测定(通过压力计法和水柱法)。
ISO 1920-2:2016 specifies procedures for testing fresh concrete. It specifies the following test methods: determination of consistence (slump test, Vebe test, degree of compactability, flow-table test for high?fluidity concrete, and the slump-flow test), determination of fresh density and determination of air content by the pressure-gauge method and by the water-column method.
