 Civil Engineering Research Journal- Juniper Publishers Opinion Last summer, the European HISER conference surprised everybody with the announcement from one of Tongji University’s top institutes that high-rise towers had been built from recycle concrete in areas of China that are prone to earth quakes. At the same conference, Francois de Larrard, research director of Lafarge Holcim, informed the attendees that, from that moment onwards, the company offered recycle mortar as a standard product and that engineers who felt insufficiently prepared for the new material could refer to their new handbook for help. The surprise was understandable because the research that led to the breakthroughs highlighted at the conference had not been well published and the few scattered results that had reached the journals did not provide a complete picture. Before the conference, most engineers had believed that it was not economically feasible to produce high-grade new concrete from end-of-life (E...

 Civil Engineering Research Journal- Juniper Publishers Abstract   In the recent years, the population has increased to use fire bricks and concrete blocks causing to raise demand and price. Further, people turn back using new techniques such as mixing the earth block with silica fume and oil palm fiber to improve compressed earth block to aid people to use it, especially people with low income. The compressed earth block has a weak resistance to compressive strength which applies on it., also has a high percentage of water absorption due to the voids in earth block. This study aimed to improve the durability and compressive strength of compressed earth block by using additives such as silica fume and oil palm fiber. In addition, to investigate which one of the additives have appropriate to obtain the highest compressive strength with reducing the percentage of voids. The purpose of this study is to mix the compressed earth block with cement and some additives such as silica f...

 Civil Engineering Research Journals- Juniper Publishers Abstract The Cape Aokas situated in the oriental coastal region of Béjaïa city (Algeria). The cape takes its origin from the babor mountain chain to the Mediterranean Sea along the Aokas city. Its relief is characterized by abrupt slopes. On May 9th, 2005 rocks fall in large mass (20,000 to 30,000m3) from one of the walls constituting the cape, blocked traffic on a busy road (RN° 9) at the entrance of Aokas city. The excavation work of fallen rocks was quickly undertaken by the authorities: 23 days after the rock fall, the road was reopened to traffic. The topometric monitoring was be implemented between April and September 2014 during the summer. The reflection was started to find the best way to strength permanently the rocky slope. In this paper, we present a comparison between the stabilizing system applied to the rocky slope and an optimization proposal in both following cases: without earthquake and under reference eart...
