Quality Requirements of Concrete Admixture

Image
Admixture is a material that is used as an ingredient for the preparation of concrete, and is added to the batch immediately prior to or during mixing materials. Admixtures are added to improve fresh or hardened concrete properties or the combination thereof. When admixtures are added it should meet some quality requirements and here we are going to discuss about which qualities are needed. Ø   Characteristic of Admixture: It is necessary to understand about the admixture, its types, forms, basic material used, details on dosage and its application methods, precaution to be taken and compliance with specified standards for using with concrete. Ø   Chemical Composition: This is an important parameter. The chemical composition such as chloride and soluble sulphate content of admixture shall comply with specification given by BIS and other organisation. Ø   S olid Content: This content is important to determine the concentration and efficiency of admixture.If h

New Technology for Concrete Testing

Image
First let’s understand what is compressive strength and why testing is important? Compressive strength is the ability of material or structure to carry the loads on its surface without any crack or deflection. A material under compression tends to reduce the size, while in tension, size elongates. Compressive strength depends on many factors such as water-cement ratio, cement strength, quality of concrete material and quality control during the production of concrete, etc. The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. So it is important to carry out the test on the field. Many cement companies have started their mobile concrete van for site testing to serve better and its boon for Construction industry because cement and concrete are the key materials for construction. This mobile lab provides technology straight to you. Now we understand how tests to be done. Firstly, this mobile concrete lab goes to t

Drones in construction

Image
Drones are very popular in the building industry as the fact that they provide an aerial view of a site at a comparatively smaller amount of the cost of the construction. It has been a major innovation in last few years. This means they can be used to develop plans, track progress and monitor any issues throughout the construction process. Drones help to track and communicate progress, track and manage materials and assets, reduce theft, improve owner visibility, increase safety, and provide valuable information for improving design changes. Here’s a look at some of the ways drones have already changed the industry and how these trends will impact construction operations in the future. Surveying Land Unmanned Aerial Vehicles (UAVs) are rapidly replacing traditional land-surveillance methods. They are growing in popularity so rapidly that some have even abandoned the classic “bird's-eye view” expression with “drones eye view.”  Drones greatly reduce the labo

Cement Manufacturing Process

Image
Cement manufacturing process involves various raw materials and processes. Cement is a greenish grey coloured powder, made of calcined mixtures of clay and limestone. When mixed with water becomes a hard and strong building material. It was first introduced by a British stone mason, Joseph Aspdin in 1824, who cooked cement in his kitchen. He heated a mixture of limestone and clay powder in his kitchen, and grind the mixture into powder creating cement, that hardens when mixed with water.  Cement is first used in the tunnel construction in the Thames River in 1828. Manufacturing Process of Cement There are four stages in this whole process. Ø   Mixing of raw material Ø   Burning Ø   Grinding Ø   Storage and packaging Mixing of raw material Calcium, Silicon, Iron and Aluminium are the raw materials used majorly in manufacture of cement. There are two methods of mixing. Dry Process and Wet Process. Ø   Dry Process: The both calcareous and argi

#Vastu For Home – Colours for Home

Image
Colours are playing an important part in the house. If we coloured each wall with same colour, it will end up looking bad therefore it is important to have a balance of colour in the entire house. Depending upon in which direction room is located best suitable colours have to decide. Each and every room in the house is different because every room has specific purpose. If we are using wrong colours at wrong places it will mess up. For master bedroom, it is advisable to use brown, blue and pink colours. Red is not advisable to use. Red colour will bring fights within the family, with neighbours. Whereas the blue and pink are masculine and feminine colours respectively and the brown colour gives stability. Use light green and light yellow colour for kid’s room that will help them to concentrate more on studies without wasting time. Avoid using dark blue colour in kid’s bedroom. For living room, use more of white colour.  You can use tinges of some other colours

#Good Construction Practices – Plastering

Image
Plaster has important requirement in fresh and hardened state. Plaster is a thin layer which is applied over masonry surface. It will give smooth, firm surface and increase the building appearance. It provides damp-proof coat on the brick masonry. Plastering is important to cover the poor workmanship and to protect wall from the atmospheric differential. Different methods used to plaster different surfaces of concrete such as dense concrete, low-weight concrete and mixed concrete. Before start plastering, concrete surface has to be free from paint, oil and dust so that plaster can bond properly. The texture of concrete surface has to be rough enough to hold the plaster. To obtain consistency slurry has to be applied over the concrete surface and this mixture is prepared by mixing 1:0.5 ratio of cement and coarse aggregates respectively. Plaster Coat which is applied over masonry work has to be 10-15 mm thick. If it is applied in only 1 layer than it must be not m
