- The reservoir properties are mainly affected by depositional settings, cement content and micro-pore structure, etc.
- Laboratory tests were carried out on two aggregate gradings with asphalt content of 7%, 8% and 9%, and with cement content of 2%, 3% and 4% respectively.
- Cement content on-line analyzer designed by energy disperse x-ray fluorescence (EDXRF) is discussed, and some key circuits are showed too.
讨论了 X荧光水泥组分在线分析仪的设计与实现 ;并给出部分硬件电路 .
- When the amount of water is fixed, GTE reduces with the increasing of water-cement ratio and increases when cement content is fixed.
- Laboratory tests were carried out on two aggregate gradings with asphalt content of 7%,8% and 9%,and with cement content of 2%,3% and 4% respectively.
- The paper studied on pavement pefformance of gravel asphalt miXture andcement stabilized sand-gravel with differ cement content, and then designparameters of them are decided.
