Welan gum is used as an additive in the cement system, owing to its low viscosity, which reduces the fluid loss of the composition. It enhances the suspension properties of cement suspensions and is much effective at low concentrations. Welan gum enhances the cement workability when it rapidly hydrates, and the admixture is often used in post-tensioning grout, proportioning underwater concrete, and self-consolidating concrete. China was the major producer of cement with the production of 2,370 million metric ton, in 2018. As per the National Bureau of Statistics of China, the revenue of the construction sector registered a CAGR of 3.75% between 2013-2017 and was valued at CNY 39,765 million in 2017. In 2019, the country’s construction industry is expected to rise by almost 6%. The real estate investment, which includes investments in the residential and commercial sector and office spaces, rose by 11.6% between January-February, in 2019, compared to the same period in the previous year. The robust investment in the property sector was supported by the steady housing prices and an increase in property construction, which would stimulate the usage of cement and enhance the demand for welan gum in the country. The construction industry in the United States continued to expand in 2019, owing to a strong economy and positive market fundamentals for commercial real estate, along with an increase in federal and state funding for public works and institutional buildings. Additionally, other factors, such as Tax Cuts and Jobs Act of 2017 and the hurricane rebuilding in the southeastern region of the United States, contributed to the increasing activities in the construction sector of the country.
