Acoustic Properties of Building Materials for Noise Control

Acoustic property of building is based on acoustic nature of building materials and how sound is transmitted through the adjacent structural elements. Noise is unwanted sound, that is considered as a nuisance in buildings for residential or domestic purposes. The buildings must possess good sound insulation property to have good acoustic feature. Sound insulation of […]

CONCRETE REPAIR QUALITY CONTROL

Quality control in concrete repair works essential to regain lost strength in concrete due to cracks or other damages. Concrete repairs are required when structural members get damaged or cracks. The reason for cracks or damages can be many. It can be due to over-stressing, poor construction practices, environmental exposures, chemical attacks or with age […]

How to compute materials in Plain Cement Concrete

This construction video will briefly teach you how to measure the binding material, fine and coarse aggregates determination for Plain Cement Concrete (PCC). Initially, the estimation is made for cement then sand and finally for crushed stone. Plain Cement Concrete (PCC) refers to the construction material that is usually applied as the binding materials. It […]

Weigh Batching vs Volume Batching

Once mix design is established, the first task is to batch materials.Batching is the process of measuring and combining required ingredients of concrete by either by weight or by volume as per the mix design and introducing them into a mixture to produce a uniform quality of concrete. The proper and accurate measurement of all […]

Building Materials Cost Estimate Sheet

To determine an accurate building materials cost estimate, the estimator should take into consideration various factors.   Different building components like roof, wall, floor etc.; items required like rebar, stud, paint, etc.; materials such as steel, pine, vinyl, etc.; the size and description of the items along with its estimated quantity and unit cost are […]

Construction Quantities of Materials Estimate

  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. cement, sand, coarse aggregates and […]

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. cement, sand, coarse aggregates and water. […]
