What is CHOPS? Where Is It Used? CHOPS involves the deliberate initiation of sand influx during the completion procedure, maintenance of sand influx during the productive life of the well, and implementation of methods to separate the sand from the oil for disposal.
Concrete is made from cement, sand, gravel and water. In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength.
3. Warm the subgrade before placing concrete on it during cold weather. 4. Avoid placing a slab directly on polyethylene film or other vapor barriers.
Method-1: DLBD method to Calculate Cement, Sand and Water required for Plaster (1:4) For calculation purposes, lets assume that the area that needs to be plastered is 100 sqft (10 ft X 10 ft wall) and a Plaster of Mix ratio 1:4 (cement:sand) is used.

Dear all Thanks for usefull info. I'm facing some problems with flyash now. I manufacture Aerated Concrete blocks with cement : Flyash ratio approx 40:60, last week i got flyash which was slightly green tinted (colour like cement). and with this flyash i made 14 batches of 0.6 Cubic meter mix.
Mayco LS40 concrete pump Variable volume output from 0 to 40 cubic yards per hour (0 to 35 m³/hr) Designed to handle the larger #/4", 1" and up to 1!./2" aggregate (38 mm)
Fine and coarse aggregates make up the bulk of a concrete mixture. Sand, natural gravel, and crushed stone are used mainly for this purpose. Recycled aggregates (from construction, demolition, and excavation waste) are increasingly used as partial replacements for natural aggregates, while a number of manufactured aggregates, including air ...
Building a hollow block perimeter wall around our Philippine lot. A first step in our Philippine house building project. Katherine Boo, writing in the February 23, 2009 edition of the New Yorker magazine makes what I feel are over-politicized theories on fences in the developing world.
Concrete CO 2 Fact Sheet JUNE 2008 4 greenhouse effect resulting from these greenhouse gases. Water vapor, the most abundant greenhouse gas, is not affected by human activity.1
Hydraulic fracturing (also fracking, fraccing, frac'ing, hydrofracturing or hydrofracking) is a well stimulation technique in which rock is fractured by a pressurized liquid.
A Table for Concrete Mixes by Weight in Kilograms, by Bag, and by Cubic Meter, for Various Strengths
Sand is a loose, fragmented, naturally-occurring material consisting of very small particles of decomposed rocks, corals, or shells. Sand is used to provide bulk, strength, and other properties to construction materials like asphalt and concrete.
Concrete mixing ratios for cement, sand, aggregate, and water are generally mixed as 1 part cement, 3 parts sand, and 3 parts aggregate or stone with just enough water to make it workable.
Hi, we are looking to rebuild our house and I'm just wondering what kind of price I can expect for the concrete slab, which is about 250m2 with a depth of 600mm. I'm new to these stuffs so please tell
Foamed concrete and foamed cement made with Allied's foam have very fine pore structure, unlike that made with conventional proteinaceous and surfactant foams.

Calculation Of Materials For Different Mix Ratio: Quantity estimation of materials is essentially required in any construction works and quantity of materials depend on the mix proportions of the concrete.

Hi Bob, how did you decide the dims for the ponke ? Converting them to my inches i make it 16ins (approx) square that gives 2.3 cubic feet. I am having a problem with working out the trips needed to the mixer with your 1.2.3. mix
The cubic meter, symbol: m³, is the SI derived unit of volume. It is the volume of a cube with edges one meter in length. That means: 1 meter in length, 1 meter in width, and 1 meter in height.
Step-1: Calculate Volume of materials required. Density of Cement = 1440 kg/cum (Approx) Volume of 1 Kg of Cement = 1/1440 = 0.000694 cum. Volume of 01 bag (50 kg) of cement = 50 X 0.000694 = 0.035 cubic meter (cum)
