crack on walls

Post by sleepzawake on Tue Mar 12, 2013 6:29 am

ngayon napapasok nako sa mundo ng construction napapansin ko na ang mga palitada po na napuruhan na ay nagbibitak pag tuyo. ngayon naging isa itong palaisipan saken. inobserbahan ko yun lumang bahay namen. kahit po walang batak ang walls niya derecho pintura lang. hinde mo makikita ang crack. taon ang binibilang bago lumabas ang crack. ngayon sandale lang, pagkaunang pahid may crack na. ano po kaya yun? hinde ba kaya dahil sa mga cemento na labas ngayon? baka po may nakakaalam. salamat po.

i think yung ratio ng cement and sand is really important, kung sobra or kulang ang cement, mag reresult ito sa crack, another thing is, yung quality ng sand, na experience na namin gumamit ng local sand dun sa beach house project namin. Nagcrack plastering namin pero nung white sand ginamit namin, minimal nalang, try mo rin gumamit ng cement for plastering lang

1. matapus ang asintada ng hollow block, dont just plaster it, let them dry for a couple of days, more or less 7 days. let the moisture inside escape naturally

2. when plastering, dont use a quick drying cement mixture.

3. use wire screen specially sa mga area na need ang makapal na plaster.

Tama silang lahat. Ang theory kasi dito is natutuyo agad ang palitada faster than the inner cement. Yung dating ginagawa ay binabasa lagi or nilalagyan ng plastic para pawisan ang pader. Same concept sa pagdilig ng mga bagong gawang kalsada few decades back.

Ang idea is dapat sabay matuyo ang inside at outside cement. Kasi pag naunang matuyo ang sa labas, tendency is magcrack dahil sa expansion na dulot ng pagtuyo ng inner part ng concrete wall.

Solution minsan is lagyan ng additives ang mix pero medyo may kamahalan ito, pero ang kapalit naman ay magandang pader.

Avoid using quick drying cement like NCC. Use Holcim WallRight, pang palitada talaga sya, konti lang naman deperensya sa presyo sir.
