What else can I help you with?
How does mixing concrete and allowing it to harden is similar to formation of sedimentary rock?
Both processes include sediments and water, with the water facilitating the setting of the material. However, sedimentary rock tends to form under pressure, whereas the hardening of concrete just requires it to dry out.
Is concrete metamorphic or sedimentary rock?
Concrete is an artificial material made by mixing cement, water, and aggregates like sand and gravel. It is not a naturally occurring rock and therefore cannot be classified as metamorphic or sedimentary.
How can you ensure that posts are set in concrete without mixing?
To ensure that posts are set in concrete without mixing, you can use pre-mixed concrete that only requires water to be added. This eliminates the need for mixing on-site and helps maintain the integrity of the concrete when setting the posts.
What is correlation between strength of mortar to strength of concrete?
mortar are mixing by sand & cement and concrete is mixing by cement, sand & stone
What are the causes of bleeding in concrete?
exceed mixing and compacting
Does mixing cement weigh the same as dried concrete?
no
What is the concrete mixing ratio in C30 concrete as per British standards?
1:2:4
Functions of water in concrate mixing?
Water in concrete mixing plays several important roles: It hydrates the cement, which allows the concrete to harden and set. It helps to lubricate and facilitate the mixing process. Water also affects the workability and flowability of the concrete, allowing it to be poured and compacted easily. Adjusting the water content can also impact the strength and durability of the final concrete.
What is the mixing ratio in M5 concrete?
1:4:8
How can concrete be strengthened?
by mixing a nano-sized additive with cement.
What are the Causes of bleeding in fresh concrete?
exceed mixing and compacting
What is light weight aggregate?
Small stones for mixing in concrete.
