Slope Failures and Remedial Measures for Strategic Highway Construction in Hilly Terrain


Dr. S.S. Seehra, Senior Consultant (Roads & Highways), LEA Associates South Asia Pvt. Ltd. (Former Director – Grade Scientist & Area Adviser, CSIR-CRRI, New Delhi) Introduction Gravitational forces are always acting on a mass of soil or rock beneath a slope. As long as the strength of the mass is equal to or greater than the gravitational forces, the forces are in balance, the mass is in equilibrium and movement does not occur. An imbalance of forces results in slope failure and movement in the forms of creep, falls, [...]

M. Shahul Hameed, Faculty & Research Scholar, Dept. of Civil Engg., Sethu Institute of Technology, Kariapatti; P. Kathirvel, Faculty & Research Scholar, Dept. of Civil Engg., KLN College of Engg., Madurai, and Dr. A.S.S. Sekar, Asst. Professor, Dept. of Civil Engg., Alagappa Chettiyar College of Engg. & Tech., Karaikudi For many decades, concrete has largely been used as a construction material, whether in moderate aggressive environment, or in strong aggressive environment. By volume alone, concrete is the world's most important construction material. Self–compacting Concrete (SCC) as the name implies that the concrete requiring a very little or no vibration to fill the form [...]

Guidelines on Repair and Rehabilitation of Structures


Samir Surlaker & Sunny Surlaker, MC-Bauchemie India Private Limited Introduction Versatility of Concrete is an established fact on account of its mouldability and durability. This makes it attractive for use in varied exposure conditions. Vulnerability of concrete to deterioration has always been a cause of deep concern. Concrete Cover plays a key role in this phenomenon. Generally, the process of deterioration begins almost immediately after the casting. Basically from material science point of view, the durability of concrete structure is a direct function of achieving specified cover not only in dimensions but also in quality. Considering a mix of complicated construction, [...]

Concrete Aggregates- From Discarded Tyre Rubber


The scarcity and availability at reasonable rates of sand and aggregate are now giving anxiety to the construction industry. Over years, deforestation and extraction of natural aggregates from river beds, lakes and other water bodies have resulted in huge environmental problems. Erosion of the existing topography usually results in flooding and landslides. Moreover, the filtration of rain water achieved by deposits of natural sand is being lost, thereby causing contamination of water reserves used for human consumption. Hence, to prevent pollution authorities are imposing more and more stringent restrictions on the extraction of natural aggregates and its crushing. The best way [...]

Concreting on moon…Waterless Concrete!


NASA plans to launch manned spacecraft to moon in 2020; but it hopes not just to land on the moon but also to establish longer-term bases for astronauts, and to accomplish this the astronauts will need to be able to build structures using resources that are readily available on the lunar surface. The structures will need to be able to withstand the harsh lunar environment, and for this reason concrete appears to be a suitable building material. Traditional concrete comprises a binder—cement and water—mixed with aggregates, but water will presumably be unavailable on the moon.  Dr. Houssam A. Toutanji, F.ASCE,  a professor at The [...]
