What Is an Alkali Aggregate Reaction Bath?<\/h1>\n

The Alkali Aggregate Reaction Bath<\/strong> is designed for conditioning mortar bar specimens used to evaluate the potential alkali-silica reactivity of aggregates<\/strong>. The bath maintains specimens in NaOH or another specified solution at a controlled temperature throughout the required test period.<\/p>\n

The system is particularly suitable for 25 \u00d7 25 \u00d7 285 mm mortar bars<\/strong>. Stable temperature conditions are important because small variations can affect expansion development and the repeatability of ASR measurements. Liya\u2019s system provides digital temperature adjustment from ambient conditions up to 100 \u00b0C<\/strong> with 0.1 \u00b0C control resolution<\/strong>.<\/p>\n

Digital Temperature Control<\/h2>\n

The operator sets the required temperature through the digital control unit. An external PT100 temperature sensor<\/strong> can also be positioned in the bath to monitor the actual liquid temperature independently.<\/p>\n

This arrangement helps laboratories maintain consistent conditioning conditions during long-duration ASR testing. It also makes it easier to verify that the bath temperature remains within the required test limits.<\/p>\n

36 and 72 Specimen Capacity Options<\/h2>\n

The product family includes two capacity configurations.<\/p>\n

The LT-A0086<\/strong> accommodates 36 mortar bar specimens<\/strong>. For laboratories with higher testing volumes, the LT-A0085<\/strong> configuration provides 2 \u00d7 36 specimen capacity<\/strong>, allowing up to 72 specimens to be conditioned.<\/p>\n

Special polyamide racks keep the specimens in a vertical position and prevent direct contact between adjacent mortar bars.<\/p>\n

Stainless Steel Construction<\/h2>\n

The bath is manufactured from stainless steel<\/strong> for resistance to water, elevated temperature and alkaline test solutions. A sealed tempered-glass cover reduces heat and liquid loss while allowing the operator to inspect the specimens.<\/p>\n

An electronic water-level monitoring system provides an alarm when the bath level becomes too low. The wheeled construction also makes repositioning within the laboratory easier.<\/p>\n

ASR Mortar Bar Testing<\/h2>\n

In accelerated mortar bar testing, specimens are prepared and their initial length is measured before exposure to the alkaline solution. Under ASTM C1260<\/strong>, mortar bars are conditioned using an accelerated procedure involving elevated temperature and 1 N NaOH solution<\/strong>. Length changes are then monitored over the specified test period.<\/p>\n

The Length Comparator<\/strong>, analog or digital dial indicator, steel inserts and 305 mm reference rod<\/strong> provide the supporting equipment required for precise dimensional measurements.<\/p>\n

Reliable Laboratory Conditioning<\/h2>\n

The Alkali Aggregate Reaction Bath<\/strong> combines accurate temperature control, durable stainless steel construction and high specimen capacity. This makes the system suitable for aggregate producers, concrete laboratories, universities and research facilities performing ASR investigations.<\/p>\n

With its digital control system and compatible length-measurement equipment, the bath provides repeatable conditioning conditions for evaluating dimensional changes in mortar bars.<\/p>\n
