Mass balance of silica in straw from the perspective of

Mass balance of silica Aman and Nordkvist (1983) reported that 57% of the silica is in leaves, which is closer to the results obtained in this study. Meanwhile, their results for silica content in the node and internode were nearly equal, but in this study it was found that the silica content in the internode was six times more than that from

silica DefinitionFacts Britannica

Silica, also called silicon dioxide, compound of the two most abundant elements in Earth’s crust, silicon and oxygen, SiO 2. The mass of Earth’s crust is 59 percent silica, the main constituent of more than 95 percent of the known rocks. Silica has three main crystalline varieties: quartz (by far the most abundant), tridymite, and cristobalite.

Alkali–silica reaction Wikipedia

The alkali–silica reaction (ASR), more commonly known as "concrete cancer", is a swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive non-crystalline silica found in many common aggregates, given sufficient moisture.. This reaction causes the expansion of the altered aggregate by the formation of a soluble and
