Potential Alkali-Silica Reactivity of Aggregates

Brand/Supplied From : Controls – Italy

Model : 48-D0545, 62-L0009/A

Standard : ASTM C289, NF P94-048, UNI 8520:22

ASTM C289 : Metode uji ini mencakup penentuan kimia terhadap potensi reaktivitas agregat dengan alkali dalam beton portland-semen yang ditunjukkan oleh jumlah reaksi selama 24 jam pada suhu 80°C antara larutan natrium hidroksida 1 N dan agregat yang telah dihancurkan dan diayak hingga lolos saringan 300 μm dan tertahan pada saringan 150 μm.

Highlights

Standar ASTM, NF, UNE dan UNI menggunakan kode wadah reaksi 48-D0545 untuk penentuan kimia potensi reaktivitas alkali-silika dari agregat yang digunakan dalam beton.

Features

• Other apparatus are also needed, for example the Jar Milles models 48-D0544 and 48-D0544/A.
• UNI 8520-22 also requires the Three gang mold 25x25x280 mm code 62L0009/A.
• The 48-D0545 container is made from stainless steel and is fit with an airtight cover.

Specifications

• Capacity:59 cm³
  Mold material: The 62-L0009/A mold is made from steel with a minimum surface hardness of HV200.
• To measure a 25 x 2 5 x 280 mm specimen, use a Length Comparator (see related products section).
