What is the world's largest concrete batch plant?
The Erie Strayer MG-12CP2, I believe, has the highest production rate of any concrete batch plant. It is used for mass concrete placements that require 700+ cubic yards of concrete delivery per hour.
Does concrete still gain strength after 28 days?
yes,up to one year. However the rate again of strength is very slow.
What is expansion contraction joint how concrete expands contracts?
Concrete expands as it gets warmer and contracts as it gets colder. Left to itself these size changes can lead to cracks occurring, if different parts of the structure heats up/cools off at a different rate than other parts. By dividing the concrete into sections separated by joints that allow for some movement the thermal stresses can be managed and the risk of the concrete cracking goes away.
What is curing of concrete?
The curing of concrete is a reaction between the type of cement in the concrete and the water. This reaction between cement and water is known as hydration. When the concrete sets and gains strength through this process it is known as curing. Test cylinders of concrete for construction projects are placed in a curing room where they are continuous misted with water at 23 +-2 degrees Celsius for 7 and 28 days before testing. This provides adequate curing.
What different of blinding concrete vs lean concrete?
a blinding concrete is a thin layer of lean concrete
What is permeability for concrete?
Permeability is defined as the property that governs the rate of flow of a fluid into a porous solid.
What is the relationship between permeability and rate of infiltration?
Permeability is the ability of a material to allow fluids to pass through it. Higher permeability means fluids can infiltrate more easily into the material, leading to a faster rate of infiltration. Conversely, lower permeability means fluids pass through at a slower rate, resulting in slower infiltration.
What is the Working principle of no fines concrete?
No-fines concrete as the term implies, is a kind of concrete from which the fine aggregate fraction has been omitted. This concrete is made up of only coarse aggregate, cement and water.Very often only single sized coarse aggregate, of size passing through 20 mm retained on 10 mm is used. No-fines concrete is becoming popular because of some of the advantages it possesses over the conventional concrete.
What is concrete types?
High density concreteSulphur infiltrated concreteVacuum concreteHeavy weight concreteLight weight concreteNo fines concrete
How does permeability affect rate and the type of weathering?
Permeability refers to how easily water can pass through rocks or soil. Higher permeability can increase the rate of weathering by allowing more water to infiltrate, carrying dissolved substances that can chemically weather the material. In general, materials with high permeability are more prone to chemical weathering, while those with low permeability are more likely to undergo physical weathering.
What is the rate at which liquid passes through the pore spaces of a rock Surplus?
The rate at which liquid passes through the pore spaces of a rock is referred to as permeability. Permeability is a measure of how easily fluids can flow through a porous material like rock. It is crucial in fields such as hydrogeology and petroleum engineering for determining the flow of fluids through subsurface formations.
What is an example of diffusion in a sentence?
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
What is rate of trimix concrete?
what rate of trimix concret
What is permeabillity of soil?
Permeability is the rate (speed) that rainwater seeps through the different layers of soil.
What is the ability of a cell membrane to allow material to pass through it called?
permeability
What is The rate at which liquids flow is called?
Viscosity is the term.
How does different tissues affect the rate of diffusion?
Different tissues have varying permeability to molecules, which impacts the rate of diffusion. Tissues with higher permeability, such as lungs or intestines, allow for faster diffusion due to more open pathways for molecules to pass through. In contrast, tissues with lower permeability, like skin or brain tissue, experience slower diffusion rates as molecules encounter barriers to passage.
