Duracrete PP fibres and Silica fumes in any concrete structure enhances many of its mechanical properties, especially for structures exposed to sudden impact or blast loading. Various tests were performed in laboratory on properties of concrete and remarkable increase in properties of concrete was observed.

Focus of presentation was to refresh and update advantages of fibre reinforced concrete (FRC) including recent developments. Application of FRC in Pakistan was discussed. In the last 14 years, consultants have successfully used FRC on major infra-structure projects. During question answer session reservations about FRC was clarified. Technical reference and international and Pakistan standards were …
Technical Committee for “Plain, Reinforced & Pre-stressed Concrete”, PSQCA adopted standard for “Fiber Reinforced Concrete” in 2011. In 2013, Civil Engineering National Standards Committee approved and endorsed “Fiber Reinforced Concrete”. Technical Committee Members include the following: NESPAK PCSIR, Karachi Director, PSQCA Civil Aviation Authority, Karachi Engineer in Chief, Pakistan Army Director Highway, Government of Sindh …
Bridges (Without Duracrete Fibre) Concrete bridge decks are subjected to vehicle’s repetitive dynamic load. Concrete by nature is brittle and susceptible to damage. Duracrete Fibre Projects Fiber reinforced concrete (FRC) develops properties to withstand repetitive load (flexural fatigue), ability to carry load after initial crack(toughness), abrasion resistance to reduce wearing of concrete surface and impact …
In school, engineers are trained to use three elements to solve a technical problem: Given, To Find and The Solutions. In the real world, the civil/structural engineer is faced with a number of additional parameters to consider. Another engineering concept, Value Engineering (VE), provides a technical solution linked with economic benefits that add definitive value …
