Q. How many kilos is a Mexican ton?
1 ton (t) is equal to 1000 kilograms (kg).
Q. Can concrete be over mixed?
– Overmixing concrete damages the quality of the concrete, tends to grind the aggregate into smaller pieces, increases the temperature of the mix, lowers the slump, decreases air entrainment, and decreases the strength of the concrete. Also, overmixing puts needless wear on the drum and blades of the transit mixer.

Q. Is concrete mixed in the truck?
Transit-mixed (also known as truck-mixed) concrete, materials are batched at a central plant and are completely mixed in the truck in transit. Transit-mixing keeps the water separate from the cement and aggregates and allows the concrete to be mixed immediately before placement at the construction site.
Q. What is a concrete truck called?
Concrete forms when you combine aggregates of sand, gravel or crushed stone, along with a paste. That paste is usually made of water and cement. So, what we call a “cement mixer” or a “cement truck” is actually called a “concrete mixer” within the construction industry.
Q. Why does a concrete truck spin?
If you’re wondering why cement trucks rotate their drum it is to keep the contents well mixed. Continuous mixing helps delay setting by not allowing any one part to get drier than the whole mass. It will still harden eventually though no matter how much you mix it.
Q. Is cement harder than concrete?
Let’s start with the basics: concrete is significantly stronger than cement. Cement is a durable material in its own right, but it simply does not compare to concrete. That’s why cement is usually used for smaller, more decorative projects.
Q. Which is the hardest cement?
PFC is an ultra-high-strength concrete whose properties can be further enhanced by incorporating steel fibers. The way in which PFC is prepared leads to very few voids in the final material, which gives it its high strength — 400 MPa can be applied to PFC before it fails, compared with 20-30 MPa for standard concrete.
Q. What is the difference between 43 grade and 53 grade cement?
Cement grade indicates the compression strength of the cement concrete after 28 days of setting. 43 Grade Cement attains compression strength of 43 Mpa (megapascals) in 28 days of setting compared to 53 Mpa attained by 53 Grade cement.
Q. What is pure cement?
Pure cement is the term given to cement that has not mixed with gravel, sand or stone. In powdered form, it comes in large grey bags. When added to water, it will turn into a viscous, grey mixture that becomes harder to mix the more you turn it.
