FACTORS AFFECTING DURABILITY OF CONCRETE

Concrete or plastic concrete is a freshly mixed material which can be molded into any shape. The relative quantities of cement, aggregates and water mixed together, control the properties of concrete in wet state as well as in hardened state. For a long time, concrete was considered to be very durable material requiring a little or no maintenance. […]

8 Factors that Affect the Workability of Fresh Concrete

Lubricating nature of workable concrete is the most important nature. Workability is dependent on the proportion of the constituent material as well as on their individual characteristics. The factors that affect the workability of concrete are given below: 01. Water Content of the Concrete Mix Water content will have important influences on the workability in […]

Concrete Mix Design Excel Sheet

  Concrete Mix Design Mix Design It is a process of selecting suitable ingredients and determining their relative proportions with the objective of producing concrete of having certain minimum workability, strength and durability as economically as possible. Requirements of concrete mix design The requirements which form the basis of selection and proportioning of mix ingredients are : a […]

Pouring & finishing concrete slabs

Concrete is one of the most economical, versatile and durable building materials available. Build a sidewalk, patio, or floor with QUIKRETE concrete mixes no matter your skill level. Project Instructions When working with cement-based products, always wear eye protection and waterproof gloves. Step 1 Prior to placing concrete forms: Construct the form with 2×4 or […]

Calculate Quantities of Materials for Concrete

Calculate Quantities of Materials for Concrete Quantities of materials for the production of required quantity of concrete of given mix proportions can be calculated by absolute volume method. This method is based on the principle that the volume of fully compacted concrete is equal to the absolute volume of all the materials of concrete, i.e. […]
