Design and building of a monk gate using mild steel plate and carbon steel valve

A design for the building of a monk gate that is safe and easy to operate was constructed for storing water in the pond as water harvesting structures, solving several purposes of farm needs such as supply of water for irrigation, cattle feed, fish production etc. The structure is made from mild steel plate and carbon steel ball valves. It functioned efficiently on installation into a monk designed for it (that has its groove)

Sealing capacity of different materials for the reclamation of cracked concrete fish tanks

The sealing capacity of latex sealant and Portland cement for the reclamatiOn of cracked concrete fish tanks was investigated for a period of three months. Concrete fish tanks (5m x 5m x lm) were divided into duplicate treatments (T1 and T2). The latex sealant was utilized in treatment 1 (T1) while Portland cement was utilized in treatment 2 (T2). The tanks were initially filled with water and the seepage rates were determined within five days and results showed that the rate of seepage was very high which led to the abandonment of the tanks. The surfaces of the tanks were cleaned thoroughly before the application of the sealant and cement. In Tl, the sealant was mixed in a ratio of 1:4:7 (sealant: water: cement) and applied with brush in two layers before the mortar was finally applied. The Portland cement was also mixed in a ratio of 1:3 (cement: plaster sand) and applied on the other two tanks in T2. The tanks were filled with water after curing for one week. The seepage rate determined in Tl was 4mm per day when the weather was clear (sunny) which may be as a result of water loss by evaporation while the seepage rate determined in T2 shows a continuous decrease of 12mm every 24 hours, irrespective of weather condition
