Concrete crushing line has been widely used in building, road and railway construction. According to the capacity, it can be divided into 50-80TH, 100-150TH, 150-200th, etc. DSMAC can offer both of stationary and mobile concrete crushing plant. Are you interesting We are always waiting for you.
Now, there are many questions why we crush concrete cubes at 28 days. And you might be asking why. I was once the person asking about this until I came to know the reason. Read further and, youll find the answer later in this blog.
You also might be asking, why we crush cubes or cylinder at 7 days. In most common concrete elements, such as columns, beams, slab-on-grades, and conventional suspended slabs, we start crushing cubes at 7 days. The reason is that it is the time the cast concrete can be loaded, and we can proceed with the following construction activities, but only if the compressive test report at 7 days has passed the condition of 80 percent of the specified strength.
Oct 15, 2019nbsp018332The dry process features a primary crusher handling material brought into the plant. This material enters the primary jaw crusher sized at 24-in. minus all material is 24 in. diameter or less and its output is 6-in. minus, which, in turn, feeds a secondary cone crusher to take that material down to 34-in., 189 in. or less depending on the crushers configuration.
Concrete elements are designed on the basis of a 28-day cube8217s crushing strength. A 28-day cube8217s strength actually represents the characteristic strength of the concrete. It is mandatory to test the concrete cubes or cylinders at the age of 28 days as per almost all building code requirements.
The mobile concrete crusher plant can eliminate obstacles caused by location, environment, and foundation configuration consequently provide simple, efficient, low-cost crushing solution. Mobile Concrete Crusher or Portable Concrete Crusher is among main products. This mobile concrete crusher plant has concrete crusher, belt conveyor.
The studies show that the characteristic strength of concrete reaches 99 at 28 days ofage. And it is said that the final strength will be achieved after 1 to 2 years. This means that a concrete slab or beam which has a specified strength of 40 megapascals or Mpa Nmm2 shall be almost attained at 28 days of age in cubes or cylinders.
In fact, configuration of our mobile sand making plants are not so different from our other types of mobile crushing plants. Reason of calling this product class as mobile sand making plant is because the crusher in the plant is vertical shaft impact crusher VSI crusher or tertiary impact crusher. CONSTMACH is the leader concrete.
Our crusher buckets make easy work of concrete debris, rubble, masonry, asphalt, natural stone and rock by crushing the material on site. Our excavator bucket crushers crush all types of inert demolition material which can be re-used on site. Cookies on the Epiroc website. Configuration conversions Fluid management solutions. Fluids.
When the cone is lifted from the concrete, the distance between the top of the cone and the top of the subsided concrete is known as the slump. The H-3637 Standard Slump Cone Set provides the basic test components, including slump cone, base plate and tamping rod, in an easy-carry configuration.
Portable concrete crusher is our business developed series of rock crushing gear, greatly broaden the area of coarse crushing, fine grinding operation concept, its style principle is standing in customers position, eliminate the broken from the location, the setting, multifarious primary configuration offers consumers obstacle, crushing.
Temporary Concrete Batching Plants manufactured by Camelway Machinery are a more economical way to produce high quality concrete mix at construction sites for or specific projects or temporary works., It adopts simple design and compact structure, reducing the initial investment cost and putting into production quickly. Over the years, it has established cooperative relationships and provided.
Multi-combined construction waste mobile crushing plant is a sort of combined crushing station that is designed to process recycled materials from demolished buildings to produce recycled aggregates that meet the quality test specification. The utilization of construction waste can reach 80 to 100 depending on the configuration of the plant.
Choosing a appropriate location of the concrete batching is critical, cause it not only affects the construction progress, but affects the quality and cost of the construction. In order to reduce the cost and facilitate the construction, the concrete batching plant should be built in a place that owns a convenient traffic. At the same time, the entrance and exit passages of the batching plant should be rationally designed.
When establishing a batching plant, a high terrain is required under the premise of ensuring the construction area of concrete plant. Consider whether the water content of the aggregate has an effect on the quality and productivity of the concrete. If the terrain is low and it is easy to accumulate water, the drainage should be designed. In addition, make full calculations on its drainage capacity to avoid water accumulation and affect output during heavy rain.
When purchasing a concrete batching plant, the theoretical productivity of the concrete plant should be larger than the production we need. For example, if projects39 required amount of concrete is 70 cubic meters per hour, then we should choose hzs90 concrete plant with a theoretical productivity of 90mh instead of hzs75 concrete plant with 75mh. Cause the theoretical yield of the concrete plant generally is smaller than the actual production.
If you are not sure which model of concrete plant to purchase, you can inform manufacturers your requirements to seek manufacturers39 professional guidance. Generally, the relevant salesperson will create a tailor-made configuration solution according to your demands.
Though the concrete batching plant uses a fully automated production process controlled by a computer, operators39 supervision is indispensable in this process. Therefore, we only need to recruit somenbspexperienced concrete plant operators.
On-site crushing is an easy, convenient and effective solution, for you and the environment. CONCRETE RECYCLING 140 million tons of concrete are recycled each year. JR RAMON practices conservation of natural resources, energy and landfill space. We recycle and resell top grade aggregate material for use in construction of commercial buildings.
With the newly improved tooth configuration utilizing a high-profile center tooth and lower profile teeth on both sides of the movable jaw, NPK concrete pulverizers can be used for both primary and secondary crushing operations.
The LF Series linear vibrating screens are designed for precise mid-section and final product screeninghellip.
Camelway Stationary Central Mix Concrete Batching Plant has been designed for produce high-qualityhellip.
Sep 02, 2019nbsp018332The vertical shaft impact crusher or VSI has a rotating shaft that runs vertically through the crushing chamber. In a standard configuration, the VSIs shaft is outfitted with wear-resistant shoes that catch and throw the feed stone against anvils that line the outside of the crushing chamber.
Jul 10, 2020nbsp018332The impact crusher can effectively treat materials with large moisture content and prevent clogging of the crusher. Therefore, when the concrete has a large moisture content, the impact crusher is the best choice. 2. The hammer crusher has less investment, large output and low power consumption. When the user has a large demand for production.
The concrete wastes, bricks and other materials that look like garbage under your feet has a great value and may become the pillars in the fields of roads, buildings, new materials, etc.
These seemingly useless concrete blocks mixed with pavement cement blocks, waste, waste rock, and garbage are only to be sorted and recycled, and then can completely turn waste into treasure and realize its economic value.
The traditional treatment method only involves the physical migration of concrete construction waste, which will bring a safety hazard, result in huge pollution of water resources, land resources and air resources, and occupy a large amount of land area.
Although this abandoned concrete construction waste is deemed to be not useful, after the treatment, it can meet the ideal material standards for engineering and construction.
1. Production of coarse and fine aggregates Combined with the strength grade of construction waste, concrete aggregates with different hardness and grain size can be processed, and can also be used for road pavement base filler.
