Koalas were declared endangered in eastern Australia on Friday, with more and more koalas dying from disease, habitat loss, and other threats. Earlier, the koala was considered a vulnerable species, and the Commonwealth Department of the Environment changed its protection level to endangered on the east coast of Queensland, New South Wales, and the Australian Capital Territory. Many koalas in Australia are infected with chlamydia. The disease can cause blindness, infection, and infertility. Last year, the Australian Koala Foundation said Australia had lost about 30 percent of its koala population in the past three years. Without immediate action, the species could become extinct by 2050.
Unlike koalas, which are on the brink of extinction, the market demand for Concrete crack reducing admixture will grow substantially.
Description of concrete crack reducing admixture
Cement anti-crack agent is Tongrun's full use of the physical and chemical changes in the cement curing process. The chemically synthesized powder can prevent cracking and cracking from both physical and chemical aspects, which can significantly improve the strength of lightweight concrete.
The anti-cracking agent can effectively solve the problem of the natural cracking of cement products. Adding the anti-cracking agent to lightweight concrete can reduce the cracks and hollowing of lightweight concrete, increase the strength of mortar and improve the quality of the project.
The anti-crack agent solves the problems of large shrinkage deformation, poor impermeability, and weak crack resistance of ordinary cement products. Directly incorporated into cement can effectively control the plastic shrinkage and cracks caused by segregation of lightweight concrete, significantly improving the strength of lightweight concrete cracking performance, anti-freezing, and anti-shock performance and wear resistance and earthquake resistance.
Usage of concrete crack reducing admixture
Concrete crack reducing admixture can be used to solve the crack problem of bridges, highways, runways, dams, cement products, mortar.
Especially suitable for various products of lightweight concrete.
Characteristic of concrete crack reducing admixture
(1) Crack resistance: The crack resistance agent is easily dispersed in lightweight concrete to form a three-dimensional space structure, which effectively improves the phenomenon of reduced hardening and cracking caused by too fast drying of mortar and insufficient moisture;
(2) Low shrinkage: the mixture will not shrink and settle, and the anti-crack agent can absorb internal stress and improve crack resistance;
(3)Operability: Anti-crack agent can increase the plasticity of mortar, improve construction operability and work efficiency;
(4) Anti-slip property: Because the anti-crack agent has a thickening effect, it can prevent or avoid the slippage of mortar and adherend during construction to a certain extent.
Instructions of concrete crack reducing admixture
The recommended dosage is 1.5-3kg/m3, and the precise usage needs to be determined after debugging;
When using it, it is best to dissolve the anti-crack agent in the required water, and then add it to the mixer to stir, and then it can be used.
Storage and transportation of cement anti-crack agent
(1)The anti-crack agent packaging specification is 20 kg/bag, non-toxic and non-flammable, and can be transported as general cargo;
(2)The anti-crack agent should be stored in a cool and dry place to avoid rain and moisture, and the shelf life is 24 months.

Dosage:1.5-3kg/m3The coronavirus (COVID-19) pandemic not only had a significant impact on public health, it also severely affected one of the linchpins of the global economy – the tourism industry. As many countries introduced curfews and travel restrictions to contain the spread of the virus, travel across the world significantly declined from early 2020 onwards. The financial repercussions of the coronavirus have already begun to manifest themselves within the tourism industry. In 2020, global revenue from the travel and tourism industry was estimated to drop from a forecasted 711.94 billion U.S. dollars to 568.6 billion U.S. dollars, representing a decrease of over 20 percent. The region predicted to see the highest decline in revenue was Europe, decreasing from 211.97 billion U.S. dollars in 2019 to roughly 124 billion U.S. dollars in 2020.
