WebMar 16, 2024 · For most exterior decorative concrete, a slump ranging from 4 to 5 inches is ideal. You want the mix to be similar in consistency to thick oatmeal, without being watery. Avoid slumps greater than 5 inches because an overly wet mix can reduce overall strength and result in a weak, porous surface. WebMix design involves : 1.Collection of samples for each of the concrete ingredients. 2.Conducting various tests for assessment of their quality parameters. 3.Preparing various trial mixes with varying proportions of the constituents with different w/c ratios. 4.Casting specimen cubes 5.Conducting crushing test for 7 days & 28 days.
