Problems solved by technology

In the "Experimental Regulations for Highway Engineering Aggregate", there are two methods for measuring the needle flake content of coarse aggregate, namely the gauge method and the vernier caliper method, but the common disadvantage of the two is that the measurement method is cumbersome

Embodiment Construction

[0013] like figure 1 As shown, a rapid determination device for flake particles of coarse aggregates includes a first scale plate 1 , a second scale plate 2 , and a baffle plate 3 . The first ruler board 1 is rectangular, the second ruler board 2 is square, the first ruler board 1 and the second ruler board 2 are rigidly and vertically connected, and the first ruler board 1 and the second ruler board 2 are provided with scale marks , the baffle plate 3 is L-shaped, the longer part of the baffle plate 3 is square, and its side length is the same as the width of the first ruler plate 1. The width of the shorter part of the baffle 3 is 1 / 5 of the width of the longer part.

[0014] There are scale lines on both sides of the first ruler plate 1, and the scale is a metric scale, and the scale unit is marked as "mm", which is accurate to mm. The two sides of the second ruler plate 2 are provided with scale lines, and its scale is 3 times of the metric scale value, and its scale uni...

Abstract

A fast determination device for elongated and flaky particles in a coarse aggregate includes a first ruler plate, a second ruler plate and a baffle plate. The first ruler plate is rectangular; the second ruler plate is square; the first ruler plate and the second ruler plate are in rigid vertical connection; the first ruler plate and the second ruler plate are provided with scale marks; the baffle plate is L-shaped; the longer portion of the baffle plate is square, and length of side is the same the width of the first ruler plate; both sides of the first ruler plate are provided scale marks in metric system, and the scale unit is identified as mm, and is accurate to the millimeter; both sides of the second ruler plate are provided scale marks, and the scale is 3 times of the scale value in metric system, and the scale unit is three times of the millimeter scale, and is accurate to three millimeters. The fast determination device for elongated and flaky particles in the coarse aggregate can meet the requirements of one by one measurement on suspected elongated and flaky stones in the coarse aggregate sample after visual inspection, and has simple, fast and accurate determination process.

Description

technical field [0001] The invention relates to a rapid determination device for flaky particles of coarse aggregate needles, which is used for the content experiment of flaky particles of coarse aggregate needles. Background technique [0002] Concrete is the main raw material in highway engineering construction, and the needle flake content of concrete coarse aggregate is an important factor affecting the performance of concrete. The workability of fresh concrete becomes worse with the increase of coarse aggregate needle flake content, The compressive strength value also decreases with the increase of the needle flake content of the coarse aggregate. Therefore, the accurate determination of the needle flake content and the evaluation of the quality of the coarse aggregate have been highly valued by all walks of life in the industry. In the "Experimental Regulations for Highway Engineering Aggregate", there are two methods for determining the needle flake content of coarse ...
