What is No-Fines Concrete? Advantages and Mix Proportion
No fines concrete is a very lightweight type of concrete that does not contain fine aggregate (or sand) in the concrete mixture. The aggregate-to-cement ratio of this type of concrete generally varies from 6: 1 to 10: 1, and the water-cement ratio is used in the range of 0.38 to 0.52.

What Are Aggregates and How Are They Used?
Using aggregate materials for concrete reduces production costs and increases the resistance of concrete mixes. Crushed aggregates make up for around 60% to 75% of the volume of concrete. These crushed aggregates significantly affect the properties of freshly-mixed and hardened concrete – making it more compact, decreasing its permeability ...

Can You Make Concrete Without Gravel?
Water activates the cement, which starts the chemical reaction and binds the ingredients together. Without all 4 ingredients concrete is impossible to make. So no, you can't make concrete without gravel. A mixture of sand and cement with water is called mortar. When wet concrete dries it becomes extremely strong, dense, durable, and porous.
