Like other countries, Australia is a developed country and is involved in doing different developmental works with the help of the machines. There has been a huge change in the modern days with the technology improving. The heavy loaded works of the men are done by the machines that are useful in doing different works. With time there are several improvements coming in this world and this has helped to do man to do work in a better way. Trucks - making the construction works easier The concrete mixing trucks are helpful at the time of construction. There are generally two types of trucks used and these are the Cement Truck Mixers and Concrete Motar Mixers. The off-road concrete mixers are used to do the tough jobs that are otherwise difficult to do. The sizes of the trucks vary from 20,000 to 30,000 pounds. It can carry a load of about 19,000 kilos in it. These are generally used in the major construction sites. The size of the machines varies on the type. The device is responsible for combining water, gravel, sand and cement. All of these are mixed in right quantity in order to prepare the mixture that is used for the construction work. The common type of concrete mixing truck consists of a revolving drum, where the mixing activity takes place. If the requirement is not too much, then portable types of mixers are used. The concrete truck mixers are used to do the works at a faster rate and to a better degree, so that the construction is firmly laid out. The concrete mixing truck has normally two, four, five or six axles. The numbers of the axles are determined by the amount of load it carries with it. The special type of concrete trucks is used to transport and mix up the concrete at the construction site. The mixture is mixed with water later on and supplied to the construction site. The truck maintains the speed and goes on mixing the materials until the perfect solution is made. The work is done at a much faster rate than that of manually. The injection pumps are another heavy machine that is used at the time of ground modification. The machines are used to create cemented soils. This method is used to treat the discreet zones of soil to the depth of 40m. Different aspects of soil are treated with the help of this process like the gravity structure, permeable capacity improving the discrete feature of the soil. The land is stabilized by injecting grout in the cement at a high pressure. Using this process the ground is dislodged and modified. The high pressure engine breaks the solid particles with the pressure of air and water. There are different types of grouting processes carried out and this include the jet grouting, permeation grouting, hydro fracture grouting, rock grouting and others.
