Shenzhen-Maoming Railway

Background

The Shenzhen-Maoming Railway is a railway within Guangdong Province, China, connecting Shenzhen City and Maoming City. It is an important part of the "Coastal Corridor," one of the main channels in China's "Eight Vertical and Eight Horizontal" high-speed railway network. After the opening of the Shenzhen-Maoming Railway, the travel time from Maoming to Guangzhou was significantly reduced. The fastest train journey time from Maoming to Guangzhou was shortened from 4 hours and 53 minutes to 2 hours and 15 minutes. The operation of the Shenzhen-Maoming Railway is of great significance for social and economic connections with the Guangdong-Hong Kong-Macao Greater Bay Area.

Project Challenge

The alkaline liquid flash setting admixture used on site has several major issues: a high dosage, poor setting effect, a rebound rate as high as 30%-40%, and serious burns to the human body caused by the alkaline. Additionally, there is a significant amount of sedimentation, with one-third of each barrel of agent being sediment. 

Due to the above conditions, construction workers have expressed strong dissatisfaction and have demanded a change of flash setting admixture. The engineering bureau has also suffered heavy losses and has indicated a desire to replace used flash setting admixture to ARIT’s products.

Solution from ARIT

After using flash setting admixture from ARIT,

(1)The amount of flash setting admixture used is half of the original amount.

(2)The rebound rate is 15%, while the original rebound rate was 25%.

(3)The construction efficiency is twice that of the previous flash setting admixture used.

(4)significantly enhance the strength of sprayed concrete.

(5)ARIT's flash setting admixture is alkali-free liquid, has no corrosive effects on the human body and are environmentally friendly for construction.
