Concrete Energy Saving Synergist

ZWR concrete energy saving synergist used in commodity concrete, were carried out experimental research and engineering application. The results show that the energy-boosters, in ensuring the overall performance of the concrete situation, as its content is 0.6% to 1% in cementitious material can reduce the amount of cement by 10% to 15%, significantly reduces production costs. Without changing the working properties and structural performance of the concrete this energy saving synergist can reduce the risk of cracking and total alkali content in concrete.


Introduction
Concrete is the largest amount of construction materials, scholars from various countries has researched on the energy conservation of concrete industry from different academic perspectives [1][2][3].
ZWR concrete energy saving synergist is a new concrete performance tuning admixtures, its content is 0.6% to 1% in cementitious material can reduce the amount of cement by 10% to 15%, significantly reduces production costs.Since the product use case in Inner Mongolia region is relatively small, its performance in the commodity concrete was studied.

Cement
This test uses a certain brand named PO42.5. key performance indicators are listed in Table 1.

Sand
Experimental sand comes from the local factories, it's main technical indicators as shown in Table 2.

Gravel
This test uses local 5-25mm continuous graded gravel; its main technical indicators are shown in Table 3.

Mineral Powder
Test uses S95 mineral powder, technical parameters as shown in Table 5.

Synergists
Test uses ZWR concrete synergists, it's technical performance as shown in Table 7.The results are shown in Table 9.The results are shown in Table 11.Workability of concrete good good

Result Analysis
(1) in this test, WZR concrete Energy Savingsynergists can reduce the amount of cement from 12 to 15 percent, making the same performance concrete( including concrete strength at 7 and 28 days ).

Synergist mechanisms
ZWR concrete Energy Saving Synergist are mixed by a number of organic chemical compound formed, it's key component enhanced by organic chemical synthesis alone and without any inorganic salts and alkali activator.Some studies [4][5][6] have shown that about 15% -20% cement in concrete are not fully hydrated, just filling the role, cannot be effectively dispersed react, actually belong to the surplus cement.
Dissolved in water, ZWR molecules lowers the surface tension of solution, so that the cement particles are better contacted with the water, accelerating wetting and penetration, reducing the number of bladders, thereby improving the impermeability, dense concrete and strength of concrete.

Conclusions
(1) ZWR synergists concrete can be significantly improved cohesiveness and pumpable of concrete, and it has good adaptability to different concrete materials.ZWR synergists content is 0.6% to 1% in cementitious material can reduce the amount of cement by 10% to 15%, significantly reduces production costs.
(2) Without changing the premise of concrete work performance and structural properties, reducing the amount of cement that can indirectly improve due to the early strength of high-strength cement-induced early concrete cracking and reduce total alkali content of concrete structures, also indirectly improve the durability of concrete.
