Nodullar

Nodullar


Nodullar aggregates are round in shape with a coarse texture, off white/ivory colored with a cellular structure inside, is pelletized and processed resulting in a light, porous, aerated modules with a tough outer shell aggregate, used for roof/heat insulation. In addition, each of the Nodullar balls also acts to form of the geometric barrier which helps to displace and irradiates heat over a larger surface area the air entrapped thus, reduces the rate of heat transfer compared with dense, natural aggregates. Resulting in the use of Nodullar in concrete improves, (i.e. reduces) the thermal conductivity. Therefore, the thermal properties of Nodullar have been used widely to improve thermal insulation in buildings and structures.

IC( Internal curing) in nodullar concrete  is the process where increased hydration of cement occurs because of the availability of additional internal moisture /water that is not part of the mixing water. Normally concrete has been cured from the outside IC is process  occurs curing from the inside out. Internal water is supplied via internal reservoirs found in wetting lightweight aggregates. Time dependant improvement in the properties  of  mineral based light weight aggregates is greater than with normal weight aggregates. The reason is better hydration of the cementious materials provided by moisture available from the slowly released reservoir of absorbed water within the pores of light weight aggregates
