Form pressure generated by self-compacting concrete

Form pressure generated by self-compacting concrete: influence of thixotropy and structural behaviour at rest. Self-compacting concrete (SCC) offers rational and fast casting process since it merely has to be poured, or pumped, into the formwork without any compaction work needed. But this can be at the cost of high form pressure.

IS 456 Most Important Point Part- 1 - We are Civil Engineers

Metakaolin IMP Point As Per IS 456 • Metakaolin having fineness between 700 to 900 m2/kg may be used as pozzolanic material in concrete. (As Per IS Code-456, P-13, Cl. No: 5.2.1.4) • Note-Metaknoline is obtained by calcination of pure or refined kaolinitic clay at a temperature between 650 o C and 850 o C, followed by grinding to achieve a fineness of 700 to 900 m2/kg.

Diesel fuel is used to transport concrete that release 0.009t CO2-e/m 3 empty returned journey is included. Onsite activities like pumping, vibrating, and finishing employed fuel is (1.5 L/m 3 pumped concrete), sometime concrete is craned instead of pumped so (2x1.5 L/m 3) to take other type of pumping into consideration and it emits 0.009t CO2

Small Concrete Batching Plant, Mini - Camelway Africa

Camelway's small concrete batching plant is widely used in some precast factory, concrete block factory, residential project and other small projects. We have many measures to help users reduce investment costs. For example, we provide a cement funnel instead of a cement silo for some projects that can only buy bagged cement.
