Concrete additives are chemicals and materials blended into the cement to alter its performance. Additives provide a specific benefit for a particular job. Liquid additives used during cement grinding improve the strength of the cement. Concrete bonding additive bonds old concrete to new for interior and exterior jobs like wall capping and resurfacing. Color additives give concrete a stylish look. Whatever the job, concrete additives help get it done.

Cold weather concrete has superior properties to concrete placed in hot weather. At low temperatures, though, concrete sets and gains strength more slowly because the cement doesn’t hydrate as fast. Setting time is increased about one-third for each 10 degree decrease in concrete temperature down to 40 degrees Fahrenheit. Accelerating admixtures can help to offset these effects of low temperatures on setting and strength gain. They should meet the requirements of ASTM C 494, Standard Specifications for Chemical Admixtures for Concrete.

Jufu provides concrete additives for cold weather and concrete additives for waterproofing, which can be widely used in Construction.

What are the advantages of fine aggregate concrete

1. As such materials have good compactness and are more stable during construction, the production efficiency is greatly improved. The key is not to vibrate in the production process, which reduces the pouring time and work intensity, and also reduces the labor cost.

2. As mentioned earlier, because there is no need for vibration, there is no noise, and people’s hands can be relaxed, which greatly improves the safety of work and improves the working atmosphere.

3. From the perspective of construction quality, there will be no bubbles on the construction surface when using this material, let alone repair. At the same time, its degree of freedom is very high, even some very complex shapes or structures with dense reinforcement can be easily poured.

What are the precautions for concrete mixing：

1. The mixing host equipped under different label conditions is different, not only that, but also depends on the type of specific materials, so as to select appropriate ingredients and equipment.

2. The use of one station or two stations depends on the specific workload. If a large amount of concrete needs to be poured at one time and the requirements for its quality are relatively high, it is better to use two sets of small mixing plants.
