    What is Setting & Hardening in concrete?

    The processes of ‘setting’ and ‘hardening’ are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be ‘set’ in that it is no longer fluid, but it may still be very weak; you may not be able to walk on it, for example. Setting is due to

  • Functions of chemical admixtures

    Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing, transporting, placing, and curing;

  • Introduction of Admixtures in concrete

    Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality. An increase in paste quality will yield higher compressive and flexural strength, lower permeability,

  • What is Micropiles?

    Micropiles, also known as minipiles, (and less commonly as pin piles, needle piles and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bar. Capacities vary depending on the micropile size and subsurface profile. Allowable micropile capacities in excess of 1,000 tons have been achieved. The micropile casing generally has

  • What Is Super Strength Pile (SS Pile)?

    Super Strength Pile or SS pile is another type of piling which has higher strength and able to carry more loads from any structure with fewer number of points. Most probably SS piles are made of prestressed or spun concrete. SS piles are constructed in round and hollow in cross section and have the lengths

  • Function of Pile Foundation

    As other types of foundations, the purpose of pile foundations is: – To transmit the buildings loads to the foundations and the ground soil layers whether these loads vertical or inclined – To install loose cohesion less soil through displacement and vibration. – To control the settlements; which can be accompanied by surface foundations. –

  • Pile foundation – need and functions

    Pile foundation is required when the soil bearing capacity is not sufficient for the structure to withstand. This is due to the soil condition or the order of bottom layers, type of loads on foundations, conditions at site and operational conditions. Many factors prevent the selection of surface foundation as a suitable foundation such as

  • Grouting work construction

    Grouting work is one technique used intensively for soil improvement. The main function is to achieve a stronger, denser and less permeable soil or rock, reduce settlement of stratum and fill the void around lower ground structures. This technique is to insert some kind of stabilizing agent into the ground by pressure grouting machine, the
