Characterization of Scoria Rock from Kisoro As an Aggregate in Concrete. by Ayebale, Sam

“…The test results on the engineering properties of scoria revealed that the material is suitable to be used as a fine aggregate and coarse aggregate as they were found to be acceptable by ASTM standards these are particle size distribution, shape classification, fineness modulus, silt content and organic impurities. The other physical properties of the scoria such as bulk density, specific gravity and absorption indicated that samples from Kisoro gave acceptable results.…”

Blockage Types and Status Evaluation of Drainage System in Highway Tunnels in Guangdong Province by LI Kejian, LIU Xiabing, WENG Jianhong, ZHOU Yu

“…In order to evaluate the blockage status of the drainage system in operational highway tunnels,this paper summarized the types of problems and blockage materials in highway tunnel drainage systems and proposed an evaluation method for blockage status based on investigations of several highway tunnels in Guangdong Province.The results primarily indicated the following:① The water leakage problems in tunnels were closely related to seasonal rainfall over time and were spatially connected to the distribution of unfavorable geological conditions such as karst.and the decline of drainage function caused by drainage system siltation was an important cause of tunnel water damage.② The types of blockage materials in the highway tunnel drainage system included silt,sand and gravel,concrete blocks or foreign matter,and crystallization or scale deposits.The proposed evaluation indicators for blockage status were as follows:filling degree,flow status,turbidity degree,and accumulation degree.③ Based on the priority division of evaluation indicators for blockage status, a blockage status evaluation method of highway tunnel drainage systems was proposed,and this method has been successfully applied to the drainage system remediation project of the Xinwu Tunnel.The research results can provide reference for the operation and maintenance of highway tunnel drainage systems.…”

Application of MIKE11 Model in River Network Area of Pearl River Delta for Water Quality Improvement by LI Qingfeng, GUO Shan, ZHANG Ruyu, YAN Xiaoman, ZHANG Xuelin

“…The water quality improvement in the river network area of the Pearl River Delta is an important part of the comprehensive management of the river basin,and it is necessary to study the compliance of water quality improvement measures.Taking the Beicun river system of Nanhai district,Foshan city in the Pearl River Delta as an example,this paper chooses COD,NH₃-N and TP as the characteristic indexes based on the MIKE11 one-dimensional hydrodynamic water quality model to study the hydrodynamic force of rivers and water quality improvement effect under different engineering schemes.The results show that measures such as pollution interception,silt removal,and water diversion can improve the overall water quality of the studied river reach in varying degrees,and thus the water quality improvement is achieved.As the projects of pollution interception and fresh water are implemented,the water quality in typical cross sections of main rivers in the Beicun river system can meet the requirement of class Ⅴ.After the implementation of water diversion and transfer,as well as CSO storage pool,the pollutant concentration in the observed cross section of seriously polluted rivers decreases by more than 70%.As a result,this paper can provide a basis for improving water quality in the river network area of the Pearl River Delta.…”
