Points To Remember Before Performing Concrete Compression Test

  In construction, a concrete compression test is performed to determine the compressive strength of a concrete slab. This implies the concrete body's ability to withstand compression without cracking or causing fractures on its surface or in its core. A push force is applied from both sides to assess its strength and ability to withstand the amount of compression without failing. The compressive strength of concrete is instilled by its constituent components, i.e., sand, cement, and comprehensive materials. The quality of the individual components combined with the water-cement ratio, curing techniques, temperature properties, and proportions of air and components determines the concrete's overall strength. Here are a few points to keep in mind before performing a concrete compression test: The ratio of concrete and water mixture should be optimum to strengthen the concrete up to 90% by day 14. There should be no excess water in the concrete because when the

GPR: Evaluating The State Of Maintenance Of The Building Coating

Typically, Ground-Penetrating Radar (GPR) is used to find applications in geographical and geological surveys. Ground-penetrating radar uses energy waves to look for variations in the substrata of the soil. However, GPR is starting to find application in various other fields, including the evaluation of coatings. Using a GPR, it is possible to check out the state of maintenance of the coating on a building. This application of ground-penetrating radars is particularly noticeable in the case of old buildings that are often historical. The various micro-climatic conditions that occur in these buildings lead to the bio-degradation of the walls and the coatings by forming moulds and efflorescence. A major issue with the degradation of monumental buildings is that they often do not occur on the surface. By the time the damage becomes visible, it may already be too late, and the recovery process becomes difficult. However, a GPR can easily detect the cracks, voids, and moisture patches th

What Is A Soil Inclinometer, And How It Works?

Among the various geotechnical equipment used for measurement purposes, a soil inclinometer is the most extensively used. It is a device used to measure the magnitude of the elevation, slope, tilt, or depression of soil concerning gravity. In the field of construction, inclinometers are also used to measure the deformation of a structure. Inclinometers are handheld devices and can be either digital or analogue. Due to its design and weight, an inclinometer is portable and easily carried to various sites. What does an inclinometer consist of? Inclinometers are mainly of two types: 1. Manual/Digital I nclinometer: These inclinometers consist of: ·        Inclinometer probe ·        Inclinometer cable reel ·        The android mobile readout unit ·        Accessories 2. In-place I nclinometer: An in-place inclinometer is made of the following parts: ·        Bottom wheel assembly ·        In-place inclinometer sensor ·        Spacer tubing ·        Placement tub
