Boric Acid Additive In Cement

Review on the addition of boron compounds to radiation shielding concrete .

 · Third mixture was prepared using borax as a boron additive, and resulted in hardened normal samples. As a result for this stage of the work, boric acid and boron frit have been excluded from any further tests, and it has been concluded that these boron compounds are not suitable for use. To study the effect of the borax on the sitting time of the bending material cement, standard Vi ...

Retarders Accelerators – Solutions for Global Business

Boric Acid is an intensifier for lignosulfonate cement retarders. It is useful at circulating temperatures over 250°F. Boric acid is normally run with MTR14 retarder.

Additive Construction with Mobile Emplacement (ACME)

cement, boric acid (set retardant*) and water –sample fractured during shipping to JSC prior to testing Lunar simulant JSC1A, stucco mix, Portland cement, and water *Set retardant used because this cement sets up very quickly and would solidify within the ACME system prior to extrusion

Experimental Investigation of NanoBoric ...

Nanoboric acid, Cement slurries 1. Introduction Oil and gas wells faced different problems during drilling, completion, and production stages [13]. One of the most challenging problems is designing a cementing operation. Growing demand for drilling HPHT wells requires enhanced slurry properties to conquer the HPHT challenges [4]. The cement slurry is a combination of cement particles, water ...

Hasegawa, M., Kimata, M. and Yaguchi, M. (2005) Effect and Behavior of Liquid Additive ...

Monoethylene glycol (MEG) and diethylene glycol (DEG) were used as glycolbased grinding aids, and anhydrous borax and boric acid were used as boron compounds in the tests. CEM I type cement production was carried out with the addition of grinding aid mixtures to Portland clinker and some gypsum in the experiments. All produced cement samples were tested for Blaine fineness, xrf elemental ...

Boric acid attack of the reinforced concrete used in Spent Fuel Pool

Besides, an additive contribution of cement paste and aggregates on the leached elements from concrete is suggested. Nevertheless, the degraded thickness ranges from 2400 µm to 2800 µm, which is significantly lower than the one obtained in cement paste at the same duration (3400 µm). This observation is quite unexpected and could indie a possible surface dissolution. Finally, reactive ...

Effect of additives on properties of magnesium phosphosilie cement .

Magnesium phosphosilie cement (MPSC) is a new type of magnesium phosphatebased cement, which is composed of magnesia, phosphate and silie materials, such as fly ash. MPSC has the characteristics of rapid setting and high early strength. In the present study, the effect of different additives, sodium tripolyphosphate (ST), borax (NB) and boric acid (BA) on the properties of MPSC .

In general, byproduct of boric acid and borate is used for production of its clinker (Yeşilmen and Gürbüz, 2012; Kunt et al., 2015). Lower CaCO 3 content in belite cement production results in ...

Borates in oilfield chemical appliions

boric acid Borate concentrations: Up to 1% in the cement Lost circulation treatments Drilling operations sometimes encounter fractures in reservoir rock formations. These can be naturally occurring or caused by earlier fracturing operations. Carbonate rocks are particularly susceptible to fracture. Rapid repair is needed to avoid the loss ...

Effects of Adding Boron Compounds to Glycol Based Grinding ...

In this study, the effect of substituting boron compounds with glycolbased grinding aids to the compressive strength performances of cement was investigated. Monoethylene glycol (MEG) and diethylene glycol (DEG) were used as glycolbased grinding aids, and anhydrous borax and boric acid were used as boron compounds in the tests. CEM I type cement production was carried out with the .
