placed between the two BS 5400 results‚ or close to the lower values. The Eurocode 2 results were usually reasonably close to the mean of the other results. The CEB-FIP-1990 results were consistently the lowest for high steel stresses and high concrete cover values. Results with varying spacing were close to Eurocode 2 results. The ACI 318 results were consistently the highest‚ being close to and

INTRODUCTION Self-compacting concrete (SCC)‚ developed first in Japan in the late 1980s‚ represents one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction

Reflective model In this report I am going to evaluate the difference between Gibbs (1988) and Kolb (1984)‚ drawing primarily on Gibbs’s reflective model. The Kolb cycle 1984 was published before Gibbs 1988‚ David A. Kolb published his conception after an experimental test on a book “Experience as the Source of learning and development” while Gibbs published his theory by developing on the existing Kolb cycle (ehow[07/10/2014]). Kolb’s theory is based on 4 cycles. It starts with doing something

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

introduction of concrete as a construction medium and the true arch as a structural component made it possible for the Romans to build strong‚ elaborate‚ expansive structures that would endure the test of time. Concrete Roman concrete‚ called opus caementicium‚ was made by mixing traditional lime mortar with stone aggregate called caementa. This material used less water and was very thick compared to modern concrete; therefore it was laid rather than poured (Roman Architecture‚ n.d.). Concrete was an important

The Concrete Operational Stage is recognized typically between the ages of 7 and 11 and is recognized by the subject developing schemes “that allow a greater understanding of such logic-based tasks as conservation‚ class inclusion‚ and seriation” (Snowman & McCown‚ 2015). This subject is also diagnosed and treated for Emotional
