Will fertilizer hurt unsealed concrete?
Unsealed concrete is porous and soaks in everything that is poured on it. Fertilizer will sock into the concrete.
Can you use white distilled vinegar to etch concrete?
Concrete is very hard. To do any good in etching it you need something very strong. Muriatic Acid is the only thing that I have found that works. How strong you mix it depends on the concrete. Some concrete that was poured with a lot of water in the mix will need less Acid. Concrete that is smooth and hard will take more. Muriatic Acid is caustic. Read the direction. Use rubber gloves; safety glasses; and a respirator. For a large project, such as a driveway or Patio. Use a plastic garbage can. Fill with 10 gallons of water. Carefully pour one gallon of Muriatic Acid into the water and mix with a wooden paddle. Take a plastic watering can and fill it with the solution. Wet your concrete with a water hose, then carefully pour the Acid solution onto the concrete. It will bubble and foam. This is the acid etching the concrete. Let it set for about 15 min. Scrub with a stiff push broom, and then rinse with a water hose. The acid will kill plants and grass. Steve Schillinger sds@knology.net = Safety Note = Make sure you put the water in the garbage can first--adding water to acid is a sure way to get splashed with concentrated acid.
How can i construct refractory castable?
Construction of Refractory CastableDuring the construction of refractory castable, special attention should be paid on pin welding, asphalt brushing, stirring of castable with water, making and fixing of mould, vibration and ramming of refractory castable, demoulding, sizes' and measuring points' accuracy, etc. Do construction strictly as material manufacturer and boiler works required.1. Installation of Pin and Claw NailsReinstall the pins missing for any reason and the pins in the area of heating surface composite melding junction before hydraulic pressure. Lengthen and reinstall the pins properly in coal mouth, material return mouth and upper inflection point of air duct furnace so that meets the required density of pins. Brush all the pre-buried metal parts and claw nails with asphalt paint (thickness > 1mm) or cover them with combustibles before casting.2. Dosing and Stirring of Castable & WaterThe dosing of refractory castable and water should be done strictly as the instructions of material manufacturer. The water should be clean, such as drinking water, ph 6-8. The mixer should be clean forced action mixer, and clean it for the next time using. Pay attention on the adding order of castable and water and its stirring time, adding water freely and prolonging of stirring time are forbidden. The water and refractory castable should be mixed evenly and stirred till smooth. Carry away the mixed casatble immediately after stirring, the castable poured out from stirring tank is disallowed to be poured into the tank and stirred again. Clean the tank after every construction for the next using, record the amount of water and refractory castable, and the stirring time.3. Checking Before Making TemplateCheck carefully whether the pin, hook nail and strutting part conform to the drawing, whether all the re-welding and is done and firm, whether the temporary metal parts have been cut off. Check whether the metal parts which should be brushed with asphalt paint meet the requirement, whether the casting place is clean, any other unrelated materials are forbidden to appear. For easy demoulding, a thin tier of partition (such as used oil) can be brushed in the mould. There can not be gaps between each two templates to avoid castable leaking out, so that also convenient for mould releasing. The refractory castable should be used up in 30 minutes after stirring, and should be casted to the required thickness in 1 time. Ram the castable till tight. For the too thick parts, cast tier by tier, while casting the upper tier, vibration bar can not touch the lower casted tier.
How do you strip forms with freshly poured concrete?
Yo what's up! This is easy you just a stick to draw or something
Who do you seem to loose breath when your about to drink a freshly poured coke?
Why?
What is curing why need to curing in buildings?
Curing in buildings is a process that is keeps freshly poured concrete from drying. It is kept at a certain temperature to keep it moist. Curing in buildings is important because it gives concrete what it needs to gain strength properly.
What is the subject and prediceatice of the workers poured more concrete?
"Prediceatice" is not a word, so this answer assumes you meant "predicate". The subject of "The workers poured more concrete" is "workers", and the predicate (verb) is "poured". "Concrete" is the direct object.
What does it mean to strike concrete?
To "strike concrete" typically refers to the process of leveling and finishing freshly poured concrete to achieve a smooth surface. This involves using a tool, often called a screed, to remove excess concrete and create a flat, even finish. Striking is crucial for ensuring proper drainage and aesthetics in concrete surfaces. Additionally, it helps eliminate air pockets and ensures a stronger bond as the concrete sets.
1 What does it means SITU concrete Construction?
insitu concrete is any concrete structure that is poured in its desired finished place. ie floor slabs of buildings because they are poured and never moved
If gasoline poured into a tank an chemical change?
Gasoline being poured into a tank is not a chemical change.
Define vibration of concrete and its importance?
Vibration is a process by which fully compacted concrete is achived.Importance:Prevents honeycombingPrevents segregation and bleeding of concreteExpuls air from concrete.
When concrete is poured around steel bars what kind of a material does it form?
reenforced concrete
Will fertilizer hurt unsealed concrete?

What are rat walls?
Concrete poured around a foundation.
What is the freezing point of concrete?
You're not supposed to pour concrete below 40ºfThere additives you can use in cold weather, and as concrete generates it's own heat as it cures, you can cover it with something insulative if it gets real cold.We've poured footings and foundations when the temp was in single digits, but you'll need to add the special "antifreeze".
