VTSYIQI Digital Penetration Mortar Strength Detector Penetration resistance detector Penetration mortar strength tester With Penetration resistance 800±8

Feature

Generality-------Penetration method is a new field detection method according to the relationship between the nail penetration depth in the mortar and mortar compression strength. Put a nail into the mortar by using the compression work spring loading. Test the nail penetration depth and convert the mortar compressive strength according to the strength-measuring curve. Penetration method has features of easy operation, high accuracy and low testing cost. It is suitable for the standard of JGJ／T1
Introductions-------Penetration resistance detector is a new product applying to the strength detection of masonry mortar. It adopts to the lever force method having light weight, easy operation and high accuracy features reduced the labor intensity of the testers, improved the detecting efficiency. It is the substitute product of the rebound method and in-situ method and its performance has reached the international leading level.
Specification-------1. Penetration resistance：800±8 2. Power stroke：20±0.1mm 3. Digital test ruler rang：20±0.01mm 4. Nail length：40mm 5. Nail diameter：3.5mm 6. Gauge groove：39.5mm
Operation-------1. Grinding the masonry brick gaps surface with grinding wheel2. Put the nail into the hole of injection rod (2) nail seat (9). The tip of the nail is outward. Screw the nail seat nut with a screw tightening wrench to fix the nail 3. One hand hold the penetrator (1) and the other hand set the long groove part of the assistor (12) in the end of the Strength slot (6).4. In the testing, press the cross-pein against the polished masonry brick gaps surface and hold the penetrator
Test point arrangement-----1. In the compressive strength of masonry mortar test, it should use a masonry components or structures which the square meter is not more than 25 m 2.2. In batch sampling, should be choose the masonry mortar built on the same floor, the same variety and the same strength grade, in meanwhile, no more than 250 m 3 masonry for a batch. The sampling quantity shall not be less than 30% of the masonry component.3. The tested mortar joint should be satiation.

Description:

Penetration resistance detection is based on the nail penetration depth of mortar (concrete) and mortar (concrete) the relationship between the compressive strength, the lever type force method, compression spring loading, the instantaneous potential energy reserves, the nail penetration to the mortar or concrete, by measuring the penetration depth of the nail and a combination of field detection method of measuring curve conversion to strength.
