Alkali-silica reaction is seen in concrete structures where reactive silica from aggregates combines with alkalis in the cement, forming a gel that expands under moist conditions, leading to cracking and degradation of the concrete over time.
alkaline olivine basalt (thin section)-Silica under saturated. Interstices filled by alkali feldspar and felsphatoid. Olivine doesn't show reaction with orthopyroxene. It has olivine in the groundmassTholeiitic basalt (thin section ): Silica over-saturated. (>51%).Common Si-rich glassy mesostasis (Intersertal texture). Frequently contains pyroxene. Groundmass no olivine.Olivine shows reaction to orthopyroxene.
Alkaline soil can increase the risk of concrete degradation through a process known as alkali-silica reaction (ASR). This reaction occurs when alkaline substances from the soil react with the silica in the concrete aggregates, causing the concrete to develop cracks and weaken over time. It is important to consider the soil conditions when designing concrete structures to prevent potential damage from ASR.
Actually, when an acid and alkali react, it is called a neutralization reaction. This reaction results in the formation of water and a salt. Combustion involves the reaction of a substance with oxygen to produce heat and light.
Acid + alkali ---> Salt + Water for exampleSodium Hydroxide + Hydrochloric Acid ---> Sodium Chloride + Water
well i dont really know this "chemistry" things, sorry i wish i could help.
The reaction between an acid and an alkali is known as a neutralization reaction. In this reaction, the acid reacts with the alkali to form water and a salt.
Neutralization is the reaction between an acid and an alkali. Neutralization usually results in the formation of a salt from the reaction.

Neutralisation, and yes that is how you spell it

The reaction between an acid and an alkali is known as a neutralization.
When an alkali and an acid mix together, they undergo a neutralization reaction. During this reaction, the hydrogen ions from the acid react with the hydroxide ions from the alkali to form water and a salt.
No gas is produced in the reaction of an acid and an alkali. In a neutralisation reaction, acid + alkali -> salt + water
Neutralization reaction occurs when an acid and an alkali react, resulting in the formation of water and a salt. This reaction typically involves the transfer of protons from the acid to the alkali, leading to the formation of a neutral solution.
This reaction is called a neutralization reaction. It involves the combination of an acid and a base (alkali) to form water and a salt.
a neutralisation reaction
When an acid and a base or an alkali react they form corresponding salt and water.
