験を行つ九〇結果は表２のとおシである。Test Example 2 (1) Conditions for Concrete Test A test was conducted by adding sodium gluconate, a commercially available water reducing agent, to each admixture. The concrete mix is slump 1
A plain concrete mix of 8 was determined, and the amount of water (4.3%) corresponding to the effect of the water reducing agent (sodium gluconate) was reduced from the plain concrete mix, and the mixture was mixed.Other concrete test conditions were the same as Test Example 1. The results of tests conducted under similar conditions are shown in Table 2.
