Concrete ratio of house construction

colorade · **on:** July 01, 2013, 07:32:23 PM

Mga ka-PT, Help naman, ask ko lang sana kung anu ang appropriate ng mixing with regards to cement, sand and gravel.. as of now nasa stage pa lang kami ng pagbuhos sa puting, tinanong ko yung foreman kung anu mixture nya, sabi saken eh 1 cement, 3 sand ang 6 gravel ginagawa nya dun sa puting... Hindi kaya masyado mahina yun? foundation kasi yun ng bahay..

Patulong din kung may idea kayo with regards sa different stages ng construction ng bahay e.i . haligi, pader, flooring, 2nd floor slab.. tnx in advance,

By the way, 2 storey yung bahay with lot area = 120 sqm (6m x 20m), floor area is around 167 sqm..

And this is a legal query because?
Do you plan to sue the foreman kung sakaling bumagsak yung bahay?

walang concrete ratio of house construction ang meron lang eh strength of materials na dapat sa kada parte ng bahay. So far ok naman ang desisyon ng foreman mo though 124 i suggest 124 ratio kasi dapat di masyado maraming buhangin kung gusto mo talaga ng solid na solid eh 125, ano ang size ng haligi kung isang ibabase mo ang footing mo? Anong class ng cement ang gamit? flooring? gumagamit ka ba ng round bars ano ang size? Sa slab naman though wala akong dimensions at kulang ako ng info ang advice ko lang sayo eh wag mong tipirin ang slab at dapat continuous ang paggawa nito...

Ok lng naman cguro ung mixture sa footing. For beams and columns, i suggest 124 ratio. Structural members kasi ung mga un.

always go for 123 ratio
or kung gusto makatipid na safe naman 136 ration good for 2 story residential yan,,..

sa mixture ng concrete meron yata 4 components,
cement
sand
gravel
water,

strength of concrete will depend on the proper ratio of the 4 components,
first to consider, when you say 123mix, ano yung ginagamit mo na sukatan ng gravel and sand, wooden box ba na with 0.3mx0.3mx0.3 dimension?

sa amin for
4000psi design, we use 123mix with 16liters water,
3000psi design we use 135mix with 18liters of water,
but this is not absolute, different brand of cement produce different concrete strength,
it is best to make a trial mix to confirm if you will reach youre desired cocnrete strength
