Do’s & Don’ts While Concreting

Concrete consists of different materials, which have different functions .The properties of concrete depends on the particular mixture of constituents. The basic constituents used to make concrete are cement, lime, water and aggregate. Do’s 01. Do hire an experienced contractor for successful concreting operation. 02. Also see that the main/general contractor hire good skilled sub/labour contractor […]

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 […]

WHY DO WE USE STEEL IN CONSTRUCTION AND NOT OTHER METALS ?

​WHY DO WE PROVIDE STEEL IN CONSTRUCTION : RCC (Reinforced Cement Concrete) is like a marriage. Both concrete and steel (i.e. rebar) need each others during structural elements are designed to withstand the load. As we knows, concrete is formed by the mixture of Portland cement, aggregates(fine and course) & water. And this results in […]

Cement Grouting (High Mobility Grouting)

Cement grouting, also known as slurry grouting or high mobility grouting, is a grouting technique that fills pores in granular soil or voids in rock or soil, with flowable particulate grouts. Depending on the application, Portland cement or microfine cement grout is injected under pressure at strategic locations either through single port or multiple port […]

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 […]

Bridge Cost Estimate Worksheet

  The Preliminary Cost Estimate Worksheet should be used to estimate the bridge cost for new and replacement bridge projects. The worksheet is based on the bridge shoulder break methodology. This methodology was established for use early in a project when bridge particulars, such as abutment heights and locations, are not known. The costs and […]

Calculate Steel Reinforcement and its quantity in Slab, Beams, Columns and Footing

RCC drawings so that you can find out the following values from the drawing : Length of the element : Cross section: No of bars Type of bars Spacing between the bars. Lap length ( horizontal/vertical) Development length Covers for footing/column/beam/slab. 2. Calculate the cutting length of the bars. ( total length – covers on […]

Two-Way Slab Design Based on ACI 318-11 using Finite Element Method

What is two way Slab? When the ratio of long span to short span is less than 2, then the slab is known as a slab spanning in two directions or two-way slab. BASIC STEPS OF TWO WAY SLAB DESIGN : 1. Choose layout and type of slab. Type of slab is strongly affected by […]

Calculate the ROI of Estimating and Takeoff Software

For most construction companies, estimating and takeoff software is a significant investment that requires careful consideration before implementing. And in companies used to relying on spreadsheets and traditional methods to estimate bids, it may feel like an uphill battle to convince the boss that automating estimating tasks is a smart move. Calculating software’s potential return […]
