In 1824, a man called Joseph Aspbin created portland cement by burning ground chalk and clay until the carbon dioxide was removed. Concrete was used in the 19th century a lot, mostly for industrial buildings.
Many people are under the impression that concrete and cement are the same thing. In actualÂ fact, cement is one of the main ingredients used to form concrete. Cement is a powdery substance which helps bind materials together. Concrete is a mixture of paste and aggregates.
Concrete is made up of three materials: water, aggregate and cement. When cement is mixed with water and aggregates it becomes a binding agent. Aggregate is grained material often made up of sand or gravel. When poured, this mix will harden into the solid material that is known as concrete.
Aggregate can be made up of a mixture of materials which are used inÂ buildingÂ and construction. It is used for mixing with cement, bitumen and other adhesives to form a concrete or mortar substance. Fine aggregate is often used when a smooth surface is desired such as a concrete slab. Coarse aggregate is used forÂ larger projects.
Spread a plastic sheet on the ground. Mix your materials on the sheet and place the stone and sand into a pile. Next, place the cement on top of the pile of sand and stone.Â Shovel the material to one side and create a new pile then repeat three times. Make a large and deep crater in the pile and add water. Fold the mix inwards with a chopping action to ensure the water spreads throughout.
This will entirely depend on the specification for your project – please use our concrete calculator to get a quote. Our volumetric concrete mixers ensure you only pay for what you need, saving money and time.
ConcreteÂ dustÂ contains high levels of crystalline silica. Inhaling this in the short term can irritate the nose and throat and cause breathing difficulties. Prolonged and repeatedÂ exposureÂ can lead to a disabling and often fatal lung disease known as silicosis.
Concrete is one of the most durable materials utilised in the modern world. ItÂ isÂ usedÂ forÂ longÂ lastingÂ structures as it does notÂ rot, rustÂ or burn. The lifespan of concrete buildings can beÂ double or even triple that of other common building materials.
Your local authority should have a record of when the house was constructed and what materials were used. When a house is made of concrete it usually has a cavity wall. The shuttered concrete layer with a concrete house is narrower than with a brick house.
Concrete contains a network of small pores and capillaries which can ultimately result in leaks and eventually cause deterioration of the structure and even mould formation- especially in warm environmentsÂ ideal for fungus. By damp-proofing the concrete this can be avoided.
If there is a layer of dust that accumulates on the concrete and enough moisture is present, mouldÂ canÂ grow on concrete. Unless the concrete surface is kept immaculatelyÂ clean, fungus will grow and spread.Â Controlling the moisture, rather than the dust, is often more effective.
Make a solution of household bleach and water and then scrub and wipe the affected area/areas. You can also buy detergent which is specifically for killing the mould spores. In order for the mould to be completed cleared you must scrub aggressively and for a sustained long period of time. Allow the detergent or bleach solution to soak in for a while to ensure that all theÂ mouldÂ is killed.
Although rarely through as a recyclable material, concrete can usually be recycled using heavy duty machines.
Yes, concrete can set in water. Concrete that is set underwater can end up being a lot stronger than concrete that is not.
Concrete is a vital part of many buildings due to its advantageous properties. It is a highly popular material to use because of its strong elements and is very common in the construction industry.
