Here, alccofine is used to enhance the mechanical properties, and a PCE-based superplasticizer (SP) is used to ensure suitable workability of concrete at a lower w/c ratio. The M30, M80, and M100 concrete were designed and selected for the laboratory studies which involve additional trial mix design and subsequent characterization.

The mix design calculations determine the batch quantities of ingredients to achieve an M80 grade concrete with a target 28-day strength of 88 N/mm2, 0.25 w/c ratio, and 75-100 mm slump. Initial slump tests show a slump of 180mm reducing to 80mm over 3 hours, indicating good workability is maintained.
Learn how to design concrete mix with high strength and low water-cement ratio using empirical graphs and tables. See a worked example of a …
So M30 means concrete mix ratio that has 30 N/mm 2 compressive strength. As simple as that. Mix Ratio is a proportion of concrete micro-ingredients such as Cement, Sand, and Coarse Aggregate. For Example, M20 means a mix ratio of 1:1.5:3 (1 part cement, 1.5 part sand & 3 part coarse aggregate) concrete which has a compressive strength of 20 …
This paper aims at comparing these major components when concrete of higher grade is used in the design and to establish that High strength concrete provides the most …
High Strength Concrete (M40 – M80) High strength concrete is used in heavy-duty construction projects, such as bridges, high-rise buildings, and highways, where the structure is exposed to high loads and stresses. The mix for high strength concrete is 1:1.5:3, with one part of cement, 1.5 parts of fine aggregates, and three parts of coarse ...
INTRODUCTION: High-quality materials are carefully chosen, and mixing patterns are adjusted to produce high-strength concrete. Due to the very low w/b ratio of 0.25 to …
