Things to Know About High-Strength Concrete

A Brief History Development In the late 1960s, high-range water reducing admixtures(superplasticizers) composed of salts of naphthalene sulfonate and melanine sulfonate were developed in Japan and Germany, respectively. The first applications in Japan were confined to high-strength precast products and cast-in-place girders and beams for bridges. In Germany, initially the objective was to develop underwater concrete mixtures possessing high fluidity without segregation. As it is possible to achieve both high … Read more…

Factors Affecting The Workability and Control of Concrete

Scanlon presents a comprehensive review of the test procedures and factors influencing the concrete workability. For obvious reasons, instead of workability it is more appropriate to consider how various factors affect consistency and cohesiveness, the workability of concrete mixtures is affected by water content, cement content, aggregate grading and other physical characteristics, admixtures, and slump loss, as discussed below. In order to get concrete, you should have a diesel engine concrete … Read more…

Concrete Requirements In the Near Future

There is no doubt that during the next 10 to 20 years, large volumes of structural materials will be needed for repair and replacement of deteriorating structures, and for building new housing and infrastructure to meet the basic needs of millions of poor migrants to towns and cities. Among the three primary materials of construction, namely portland-cement concrete, steel, and timber, concrete is the most adaptable structural material for use … Read more…

Properties Of Hardened Concrete

The selection of an engineering material for a particular application has to take into account its ability to withstand the applied force. Traditionally, the deformation occurring as a result of applied load is expressed as strain, which is defined as the change in length per unit length; the load is expressed as stress, which is defined as the force per unit area. Depending on how the stress is acting on … Read more…

Components Of Modern Concrete

Although composition and properties of materials used for making concrete are discussed. Here it is useful to define concrete and the principal concrete-making components. Concrete is a composite material that consists essentially of a binding medium within which are embedded particles or fragments of aggregate. In hydraulic-cement concrete, the binder is formed from a mixture of hydraulic cement and water. The self loading mixer can mix concrete evenly. It is … Read more…

Methods Of Mixing Concrete- Twin Shaft Concrete Mixer

There are two methods used for mixing the ingredients: hand and machine. Twin shaft concrete mixer is one kind of compulsory type concrete mixer. The mixer will be helpful for your construction jobs. It is important no matter which method is employed, all materials- water, cement, sand, and gravel- must be measured. Only a limited amount of water should be used when making a concrete mix. If too much water … Read more…

The Safety Operating Principles For Concrete Trailer Pump

The trailer concrete pump is a common pump in construction site. In working process, it is used to pump high pressure fluids. Therefore, you should be careful when you operate it. Here are some safety principles before operating. 1. Check the position of trailer pump. The concrete trailer pumps should be placed on the ground of horizontal and dense. 2. You should pay attention to whether the way of concrete … Read more…

Why The Price Lists Of Concrete Batching Plant Have Big Difference?

Each set of concrete batching plant equipment is customized in the light of the actual requirements of customers. The engineering concrete batching plant is mainly used to satisfy engineering needs. You don’t need to buy some extra spare parts which you may not use during production. While, commercial concrete batching plant should be capable of manufacturing various types of concrete. Also, the control system should be fully automatic. When you … Read more…
