According to ASTM and BS specifications, aggregate crushing value (ACV) and los angles abrasion test (LAAT) have been performed in the laboratory for coarse aggregates. The spatial variations in the properties of coarse and fine aggregates have been observed during this study for all the tests.
The test techniques specified include the 10% Fines Aggregate Crushing Value (10%FACT) which is a wet and dry crushing test, the Durability Mill Index (Sampson and Netterberg, 1989), which is a wet abrasion and impact test and a water soaking disintegration test. For basic crystalline materials in particular, only

With technological advancement on the rise, manual crushing of bricks is gradually being replaced by machine crushing to obtain coarse aggregates for construction. However, properties of the brick aggregates obtained from these two methods vary which in turn, may affect the properties of the concrete matrix as well. This study …
After analyzing the test results, we found that the average Aggregate Impact Value for CDW and Conventional Aggregate (CA) are respectively 29.52% and 23.87%, Aggregate Crushing value for CDW and ...
Our coarse aggregate (stones) has some unique features that separate them from the norm. Our imported stones are tested and certified by Bangladesh University of Engineering and Technology, BUET by ASTM method consisting of: Sieve Analysis (CA)/Gradation Aggregate Crushing Value/Compressive Strength Elongation Index/Shape Test …
Reading time: 5 minutes. The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. The aggregates may be natural, manufactured, or recycled. Fig 1: Aggregates used in production of concrete. The aggregates are broadly classified …
aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, there is another recommended method. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per cent fines value described in BS 812-111 is applicable.
Scope. 1.1 This specification covers the quality and sizes of crushed stone, crushed slag, crushed expanded shale, crushed expanded clay, crushed expanded slate, and crushed or uncrushed gravel suitable for use as aggregate in single or multiple asphalt surface treatments. 1.2 The text of this standard references notes and footnotes which ...
This study examines the mechanical and durability properties of five different concrete mixes using the construction and demolition waste as partial replacement of coarse aggregate. In the concrete mixes, a constant water–cement (w/c) ratio of 0.43 was used. In contrast, the natural coarse aggregates were replaced by recycled coarse …
The physico-mechanical properties of the aggregates are shown in Table 1, and the particle size distribution curves for the fine and coarse aggregate are presented in Fig. 1a, b, respectively. Figure 1a shows that the size of the fine aggre-gates is in the range of 0.15–4.75mm and about 50% of the fine aggregates are with sizes larger than ...

The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod of circular cross-section 16mm diameter and 45 to 60
Scope. 1.1 This test method covers the approximate determination of clay lumps and friable particles in aggregates. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the …
The specifications of the aggregate samples are kept similar for all of these three test procedures. The result indicates a strong correlation of Light compaction values (LCV) with Aggregate crushing values (ACV) and Aggregate Impact Values (AIV). The R2 values for the relationship was found to be more than 0.9 for both these relationships.
In this study, coconut shell aggregate (CSA) was used in brick aggregate concrete (BAC) to produce structural lightweight concrete. Various BACs containing CSA (CSBACs) were prepared based on the …
