New shipment for HT-225 concrete test hammer

1.Technical information of HT -225 concrete test hammer
2.Specification details of HT -225 concrete test hammer
3.How to use f HT -225 concrete test hammer

1. Use a grinding stone to smoothen the test surface

2. Perform a few test impacts with the rebound hammer on this smooth, hard surface before taking any measurements which you are going to evaluate. Perform a consistency check on the test anvil

3.Ensure all settings are correctly done.

4 Position the hammer perpendicular to and against the test surface. Push the concrete test hammer adainst the surface at a moderate spped until the impact is triggered. Bes aware that the plunger generates a recoil when it deploys. Therefore it is recommentded to hold the rebound hammer with both hands, perpendicular to the test surface, before triggering the impact.

5. Each test surface should be tested with at least 12 impacts dropping the highest and the lowest and then take the average of the remaining. The individual impact points must be spaced at least 25mm apart.

6. Interpret the test results.

Deep Foundation Types And Introduction

Deep Foundation Types And Introduction Deep Foundations In case, the strata of good bearing capacity is not available near the ground, the foundation of the structure has to be taken deep with the purpose of attaining a bearing stratum which is suitable in all respects.In addition there may be many other conditions which may require deep foundations for ensuring stability and durability of a structure. For example, the foundation for a bridge pier must be placed below the scour depth, although suitable bearing stratum may exist at a higher level. The most common forms of construction pertaining to deep foundations are 1) Piles 2) Caissons 3) Basement or Hollow Box Foundation Piles A pile is basically a long cylinder of a strong material such as concrete that is pushed into the ground to act as a steady support for structures built on top of it. Pile foundation is required when the soil bearing capacity is not sufficient for the structure to withstand. This is due to

How to use the THA620X Rebar Detector,rebar locator

图片
1.1Brief Introduction of  THA620X Rebar Detector,rebar locator The first generation portable rebar integrated detector THA620X uses an electromagnetic induction method, which can detect the rebar location and cover thickness & diameter accurately, store, transfer and analyze the real time test data. The model THA620X is the pinnacle of work with the modern simple design, incorporating the handy & durable features and sophisticated electronic technology. THA620X series rebar detector is mainly used to test the location, distribution, direction, the thickness of rebar and the diameter of cover in concrete structure such as walls,columns, beam-slabs etc. It can also detect the location of pipelines and metal embedded parts. The multiple coil structure design make it more accurate＆responsive and higher resolution. 1.2 Application Range of THA620X  Rebar Detector,rebar locator (1). Testing the location, distribution, direction, and diameter of the rebar and the thicknes
