Production method for non-bearing concrete hollow bricks

Abstract

The invention discloses a production method for non-bearing concrete hollow bricks, which has the characteristic of being capable of lowering the production cost. The production method comprises the steps as follows: a. adding cement, pulverized fuel ash and high-titanium heavy cinder aggregate in a blender, wherein the total weight of the cement, pulverized fuel ash and high-titanium heavy cinder aggregate is t, and the weight of the cement is 10 percent of t, the weight of the pulverized fuel ash is 25-30 percent of t and the weight of the high-titanium heavy cinder aggregate is 60-65 percent of t; and at the same, adding water with the weight of 10-12 percent of t in the blender for blending; b. adding the blending materials in pressing equipment to be vibrated, compacted and formed into concrete hollow bricks; c. placing the formed concrete hollow bricks on a backing plate for curing for 24 hours to 48 hours; and d. stacking the concrete hollow bricks on the ground for natural curing for 28 days, thus obtaining the finished concrete hollow bricks. With the use of the production method, for the finished concrete hollow bricks, the density is low, the strength is high and the production cost can be lowered.

Description

technical field [0001] The invention relates to a production method of a concrete structure, in particular to a production method of a non-load-bearing concrete hollow brick. Background technique [0002] At present, the solid waste produced after using vanadium-titanium-magnetite ironmaking is called high-titanium blast furnace slag, which is different from ordinary blast furnace slag, and its water quenching activity is low. Derivatives. [0003] The country issued the standard for non-load-bearing concrete hollow bricks in 2008, which is suitable for concrete hollow bricks used in non-load-bearing parts of industrial and civil buildings. material. [0004] The patent application titled "Method for Manufacturing Full Slag Concrete Hollow Block" (notification number: CN1056858) proposes to use blast furnace heavy slag as aggregate to prepare concrete hollow block. But it has the following disadvantages: 1. The amount of cement is high, reaching 15%, and admixtures such a...

Problems solved by technology

But it has the following disadvantages: 1. The amount of cement is high, reaching 15%, and admixtures such as triethanolamine and ferrous sulfate need to be added, and the cost is relatively high; 2. When curing, it is necessary to enter the curing kiln for steam curing first, and then natural curing. The maintenance process is cumbersome; 3. The density of the formed block is relatively high, reaching more than 1200kg / m3
