Solu-Cal PLUS - Premium Enhanced Calcitic Lime is an excellent choice for maintaining your grass. It combines the strength of pellet limestone with a boost in calcium. Solu-Cal is far more efficient than lime, and it may be used in as short as a few weeks against 6-8 months for dolomitic limestone.
Hydrated Lime is a dry powder mainly composed of calcium hydroxide Ca(OH)2. It is a colorless or white powder, which is obtained by hydrating Quicklime (Calcium Oxide) using specific equipment called hydrator in a process called hydration.The process converts CaO to Ca(OH) 2. Actually, hydration is a chemical process in which water molecules …

In samples LC2(A)-40 (30% LC2, Ra/c 0.40, with additive) and LC2(A)-45 (30% LC2, Ra/c 0.45, with additive) the effect of the additive is evident in the first 10 h. The curves have a behavior similar to the samples that do not have additive, with the difference that in the latter there is an increase in volume variation of 0.005 ml/g.
